Who is Ali bin abi Talib explain in brief?

`Ali ibn Abi Talib `Abd Manaf ibn `Abd al-Muttalib ibn Hashim ibn `Abd Manaf, Abu al-Hasan al-Qurashi al-Hashimi (d. 40), Amîr al-Mu'minîn, the first male believer in Islam, the Prophet's standard-bearer in battle, the Door of the City of Knowledge, the most judicious of the Companions, and the "Possessor of a wise heart and enquiring tongue." The Prophet nicknamed him Abu Turâb or Father of Dust. His mother was Fatima bint Asad, whom the Prophet called his own mother and at whose grave he made a remarkable intercession. He accepted Islam when he was eight, or nine, or fourteen, depending on the narrations, but it is established from Ibn `Abbas that he was the first male Muslim after the Prophet, Khadija being the first Muslim. He was killed at age fifty-eight. From him narrated Abu Bakr, `Umar, his sons al-Hasan and al-Husayn, Ibn `Abbas, `Abd Allah ibn al-Zubayr, and countless others.`Ali was a skilled and fearless fighter, and the Prophet gave him his standard to carry on the day of Badr and in subsequent battles. At the same time he was the repository of Prophetic wisdom among the Companions. The latter, when asked about difficult legal rulings, deferred to others the responsibility of answering, while `Ali, alone among them, used to say: "Ask me." `Umar said: "I seek refuge in Allah from a problem which Abu al-Hasan cannot solve." Similarly `A'isha said: "He is the most knowledgeable about the Sunna among those who remain," and Ibn `Abbas: "If a trustworthy source tells us of a fatwa by `Ali, we do not seek any further concerning it." Sulayman al-Ahmusi narrated from his father that `Ali said: "By Allah! No verse was ever revealed except I knew the reason for which it was revealed and in what place and concerning whom. Verily my Lord has bestowed upon me a wise heart and a speaking tongue." At the same time `Ali humbly declared: "What cools my liver most, if I am asked something I know not, is to say: 'Allah knows best'."Imam Ahmad said: "There is no Companion concerning whom are reported as many merits as `Ali ibn Abi Talib." Following are some of the hadiths to that effect.On the eve of the campaign of Khaybar, the Prophet said: "I shall give the standard to a man who loves Allah and His Messenger, and whom Allah loves and also His Messenger." `Umar said: "I never liked to be entrusted leadership before that day." The next day the Prophet summoned `Ali and gave him the flag.Salama ibn `Amr narrated that the day of Khaybar, the Prophet summoned `Ali who came led by the hand, as he was suffering from inflammation of the eyes. The Prophet then blew on his eyes and gave him the flag. Another version states that Ibn Abi Layla told his father to ask `Ali why he wore summer clothes in winter and winter clothes in summer. `Ali said: "The day of Khaybar the Prophet summoned me when my eyes were sore. I said to him: 'O Messenger of Allah! I have ophtalmia.' He blew on my eyes and said: 'O Allah! remove from him hot and cold.' I never felt hot nor cold after that day."The Prophet left `Ali behind in the campaign of Tabuk. The latter said: "O Messenger of Allah! Are you leaving me behind with the women and children?" The Prophet replied: "Are you not happy to stand next to me like Harun next to Musa, save that there is no Prophet after me?"The Prophet said: "I am the city of knowledge and `Ali is its gate." Another version states: "I am the house of wisdom and `Ali is its gate."When Allah revealed the verse: "Come! We will summon our sons and your sons, and our women and your women, and ourselves and yourselves, then we will pray humbly and invoke the curse of Allah upon those who lie" (3:61), the Prophet summoned `Ali, Fatima, Hasan, and Husayn, and said: "O Allah! These are my Family."The Prophet said: "Anyone whose protecting friend (mawla)I am, `Ali is his protecting friend." `Umar said: "Congratulations, O `Ali! You have become the protecting friend of every single believer."The Prophet said: "`Ali is part of me and I am part of `Ali! No-one conveys something on my behalf except I or he." The context of this hadith was the conveyance of Sura Bara'a to the Quraysh and the rescinding of the Prophet's pact with them. The scholars have explained that the Prophet's phrase "X is part of me and I am part of X" is a hyperbole signifying oneness of path and agreement in obeying Allah. The Prophet said that phrase also about the following: the Companion Julaybib who was found dead after a battle next to seven enemies killed by him; the Ash`aris; and the Banu Najya.Some people complained to the Prophet about `Ali, whereupon he stood and said: "Do not accuse `Ali of anything! By Allah, he is truly a little rough (la'ukhayshan) in Allah's cause."When the Prophet sent `Ali to Yemen the latter said: "O Messenger of Allah, you are sending me to people who are older than me so that I judge between them!" The Prophet said: "Go, for verily Allah shall empower your tongue and guide your heart." `Ali said: "After that I never felt doubt as to what judgment I should pass between two parties."The Prophet said: "The most compassionate of my Community towards my Community is Abu Bakr; the staunchest in Allah's Religion is `Umar; the most truthful in his modesty is `Uthman, and the best in judgment is `Ali." `Umar said: "`Ali is the best in judgment among us, and Ubayy is the most proficient at the Qur'anic readings." Ibn Mas`ud similarly said: "We used to say that the best in judgment among the people of Madina was `Ali." It is a measure of al-Hasan al-Basri's greatness that `Ali once followed his recommendation in a judicial case.`Amr ibn Sha's al-Aslami complained about `Ali upon returning from Yemen where he had accompanied him. News of it reached the Prophet who said: "O `Amr! By Allah, you have done me harm." `Amr said: "I seek refuge in Allah from harming you, O Messenger of Allah!" He said: "But you did. Whoever harms `Ali harms me." The Prophet also used the terms "Whoever harms X has harmed me" about his uncle al-`Abbas.Umm Salama said to Abu `Abd Allah al-Jadali: "Is Allah's Messenger being insulted among you?! [in Kufa]" He said: "Allah forbid!" She said: "I heard Allah's Messenger say: 'Whoso insults `Ali, insults me.'"`Ali said: "In truth the Prophet has made a covenant with me saying: 'None loves you except a believer, and none hates you except a hypocrite." Abu Sa`id al-Khudri subsequently said: "In truth we recognized the hypocrites by their hatred for `Ali." Jabir said: "We did not know the hypocrites of this Community except by their hatred for `Ali."The innovations of those who bore excessive love and admiration for `Ali appeared in his own lifetime and he himself fought them in word and deed. To those that claimed that the Prophet had appointed him as successor after him he said: "In truth, Allah's Messenger did not appoint any successor" and: "The Prophet was taken from us, then Abu Bakr was made the successor, so he did as the Prophet had done and according to his path until Allah took him from us; then `Umar was made the successor, so he did as the Prophet had done and according to his path until Allah took him from us." To those that claimed that he deserved the Caliphate better than Abu Bakr and `Umar he said: "The best of this Community after its Prophet are Abu Bakr and `Umar." To those that either hated him or overly loved him `Ali said: "Two types of people shall perish concerning me: a hater who forges lies about me, and a lover who over-praises me." To those that claimed that he or his family possessed other than the Qur'an which all Muslims had he said: "Whoever claims that we have something which we read other than the Qur'an has lied." Finally, when a group of people came to him saying: "You are He, you are our Lord! (anta Hû anta Rabbuna)" he had them executed and then ordered the bodies burnt.When `Ali was given allegiance as Caliph he moved from Madina to Kufa in Iraq and made it his capital. His tenure lasted five years (35-40) marred by three great dissensions which tore apart the fabric of the Muslim Community: the battle of the Camel (year 36) against the party of `A'isha the Mother of the Believers, the battle of Siffin (year 37) aganst the party of Mu`awiya ibn Abi Sufyan, and the campaign against the Khawârij in the following two years, until he was assassinated by one of them in Kufa as he came out for the dawn prayer. The pretext for the meeting of the armies on the day of the Camel and the day of Siffin was the demand for `Uthman's killers on the part of `A'isha and Mu`awiya, but the winds of war were fanned by sowers of discord from inside all three camps until events escaped the control of the Companions. It is related that `Ali often expressed astonishment at the dissension and opposition that surrounded him. The Prophet had predicted these events, notably the battle of the Camel with the words: "One of you women shall come out riding a long-haired camel, and the dogs of Haw'ab [between Mecca and Basra] will bark at her. Many shall be killed to her right and her left, and she shall escape after near death." At any rate, Ahl al-Sunna adopted as theirs the position taken by one of the Salaf who said: "Those from whose blood Allah has kept our swords pure, we shall not soil our tongues with their slander." The most reliable book written on the divergences of the Companions is Abu Bakr ibn al-`Arabi's (d. 543) al-`Awasim min al-Qawasim fi Tahqiq Mawaqif al-Sahaba Ba`da Wafati al-Nabi Sallallahu `Alayhi WA Sallam.Another innovation fought by `Ali was that of the Khawârij or "Seceders," also known as Hurûriyya after the village of Hurur, near Kufa, where they set up military quarters. They were originally a group of up to twenty thousand pious worshippers and memorizers of the Qur'an (`ubbâd WA qurrâ') who were part of `Ali's army but walked out on him after he accepted arbitration in the crises with Mu`awiya ibn Abi Sufyan and `A'isha the Mother of the Believers. Their strict position was on the basis of the verse "The decision rests with Allah only" (6:57, 12:40, 12:67). `Ali said: "A word of truth by which falsehood is sought!" He sent them the expert interpreter of the Qur'an among the Companions, Ibn `Abbas, who recited to them the verses "The judge is to be two men among you known for justice" (5:95) and "Appoint an arbiter from his folk and an arbiter from her folk" (4:35) then said: "Allah has thereby entrusted arbitration to men, although if He had wished to decide He would have decided. And is the sanctity of the Community of Muhammad not greater than that of a man and a woman?" Hearing this, four thousand of the Khawârij came back with him while the rest either left the field or persisted in their enmity and were killed in the battles of Nahrawan (year 38) and al-Nukhayla (year 39).The Prophet had predicted that `Ali would fight the Khawârij with the words: "In truth there will be, among you, one who shall fight over the interpretation of the Qur'an just as I fought over its revelation." Abu Bakr and `Umar asked: "Am I he?" The Prophet said: "No, it is the one who is mending the shoes." He had given his shoes to `Ali to mend. The Prophet also predicted `Ali's martyrdom with the words: "This shall be dyed red from this" and he pointed to `Ali's beard and head respectively.The Khawârij are the first doctrinal innovators in Islam. They considered all sinners apostates, as well as all those who opposed them. By this takfîr, they justified to themselves the killing and spoliation of Muslims including women and children. Muslims who joined them were forced to first declare themseves disbelievers then enter Islam again. They distinguished themselves by shaving their heads out of austerity, a practice which they innovated and which the Prophet had foretold. Yet the Khawârij deemed themselves scrupulously pious and the only true Muslims on earth. When `Ali's murderer, `Abd al-Rahman ibn Muljam al-Muradi, was dismembered and blinded he remained impassive and recited the Sura "Recite! In the Name of Thy Lord"(96:1) in its entirety, but when they moved to pull out his tongue he resisted; asked for the reason he said: "I hate to spend a single moment on earth not mentioning Allah." He was then executed and burnt. His forehead bore the trace of frequent prostration.The Khawârij pre-dated the Rawâfid in their vilification of Abu Bakr and `Umar. `Ali declared it licit to fight them because they had killed the Companion Khabbab ibn al-Arathth and his wife for praising the four Caliphs. The Prophet had predicted their appearance in many hadiths. Among them:`Ali sent the Prophet a treasure which the latter proceeded to distribute. The Quraysh became angry and said: "He is giving to the nobility of Najd and leaving us out!" The Prophet said: "I am only trying to win their hearts over to us." Then a man came with sunken eyes, protruding cheeks, big forehead, profuse beard, and shaven head. He said: "Fear Allah, O Muhammad!" The Prophet replied: "And who shall obey Allah if I disobey him? Does Allah trust me with the people of the earth, so that you should not trust me?" One of the Companions û Khalid ibn Walid û asked permission to kill the man but the Prophet did not give it. He said: "Out of that man's seed shall come a people who will recite the Qur'an but it will not go past their throats. They will pass through religion the way an arrow passes through its quarry. They shall kill the Muslims and leave the idolaters alone. If I live to see them, verily I shall kill them the way the tribe of `Ad was killed." Ibn Taymiyya cited this hadith as proof that the Khawârij shaved their heads."The Khawârij are the dogs of Hell-fire."`Ali was described as having white hair which he parted in the middle, a very large white beard, and large, heavy eyes. He was heavyset and his height was medium to short. He was blunt in his renunciation of the world even in his own dress. When Ibn al-Nabbah came to him with the news that the treasury-house was filled with gold and silver `Ali summoned the people of Kufa and distributed everything to them with the words: "O Yellow, O White! Go fool other than me." Then he ordered the treasury-house swept, and he prayed two rak`a in it. Jurmuz said: "I saw `Ali coming out of his palace wearing a waist-cloth that reached to the middle of his shank and an outer garment tucked up at the sleeves, walking in the marketplace while hitting a small drum (dirra) and enjoining upon people Godwariness and honesty in transactions. He would say: 'Observe good measure and do not bloat up the meat.'" When one of the Khawârij criticized him for what he was wearing, he said: "What do you want with my clothing? This is farther from arrogance and more suitable for me as I am imitated by Muslims."Al-Hasan ibn `Ali narrated that the morning of his murder `Ali said: "Last night I woke up my family [to pray] because it was the night before Jum`a and the morning of Badr û the seventeenth of Ramadan û then I dozed off and the Prophet came before me. I said: 'O Messenger of Allah! What crookedness and contention have I found coming from your Community!' He said: 'Supplicate against them.' I said: 'O Allah! Substitute them with something that will be better for me, and substitute me with something that will be worse for them.'" Then `Ali went out to pray preceded by the mu'adhdhin Ibn al-Nabbah and followed by al-Hasan. `Ali came out of the gateway calling the people to prayer and was faced by two men armed with swords. Ibn Muljam struck him on the head with a poisoned sword and was caught, while the other hit the arch of the gate and fled. `Ali said: "Feed the prisoner and give him water, if I live I shall decide about him, and if I die, kill him as I was killed without further enmity. 'Lo! Allah loves not aggressors' (2:190, 5:87, 7:55)."It was decided to make `Ali's grave a secret lest the Khawârij dig it up. After his son al-Hasan prayed the funeral prayer over him, he was buried at the Caliphal palace in Kufa, then all traces of his grave were effaced. It is also narrated that al-Hasan conveyed the body in a coffin to Madina and that on the way the camel that carried the coffin got lost by night and was found by members of the Tayyi' tribe who buried the body and slaughtered the camel.Among `Ali's sayings narrated by Abu Nu`aym with his chains:From al-Husayn ibn `Ali: "The most sincere of people in their actions and the most knowledgeable of Allah are those who are strongest in their love and awe for the sanctity of the people of lâ ilâha illallâh."From `Abd Khayr: "Goodness does not consist in having much property and children, but in doing many good deeds, increasing your gentle character, and adorning yourself before people with the worship of your Lord. Then, if you do well, glorify Allah; if you do ill, ask forgiveness of Him. There is no good in the world except for two types of people: someone who sins and then follows up with repentence, and someone who races to do good deeds. What is done in Godwariness is never little, and how can something be little if accepted by Allah?"From Abu al-Zaghl: "Remember five instructions from me in following which you shall sooner exhaust your camels than run out of their benefit: let no servant hope for anything except from his Lord; let him not fear anything except his own sin; let no ignorant person feel ashamed to ask about what he knows not; let no knowledgeable person, if asked about what he knows not, feel ashamed to say Allah knows best; and patience is in relation to belief like the head to the body, one has no belief if he has no patience."From Muhajir ibn `Umayr: "What I fear most is the hankering after idle desires and long hopes. The former blocks one from the truth and the latter causes forgetfulness of the hereafter. In truth the world has gone its way out, in truth the hereafter has come journeying to us û and each of the two has its own sons. Therefore be a son of the hereafter and do not be a son of the world! Today there are deeds without accounts, and tomorrow, accounts without deeds."From Abu Araka: "I have seen a remnant of the Companions of Allah's Messenger. I see no-one that resembles them. By Allah! They used to rise in the morning disheveled, dust-covered, pale, with something between their eyes like goat's knees, as they had spent the night chanting Allah's Book, turning from their feet to their foreheads. If Allah was mentioned they swayed the way trees sway on a windy day, then their eyes poured out tears until û by Allah! û they soaked their clothes. By Allah! It is as if folks today sleep in indifference."From al-Hasan ibn `Ali: "Blessed is the servant that cries constantly to Allah, who has known people while they have not known him, and Allah has marked him with His contentment. These are the true beacons of guidance. Allah repels from them every wrongful dissension and shall enter them into His own mercy. They are not the wasteful tale-bearers nor the ill-mannered self-displayers."From `Asim ibn Damura: "The true, the real faqîh is he who does not push people to despair from Allah's mercy, nor lulls them into a false sense of safety from His Punishment, nor gives them licenses to disobey Allah, nor leaves the Qur'an for something else. There is no good in worship devoid of knowledge, nor in knowledge devoid of understanding, nor in inattentive recitation." This is comparable to al-Hasan al-Basri's own definition: "Have you ever seen a faqîh? The faqîh is he who has renounced the world, longs for the hereafter, possesses insight in his Religion, and worships his Lord without cease."From `Amr ibn Murra: "Be wellsprings of the Science and beacons in the night, wearing old clothes but possessing new hearts for which you shall be known in the heaven and remembered on the earth.""This world lasts for an hour: Spend it in obedience.""Thus does Knowledge die: when those who possess it die. By Allah, I do swear it! The earth will never be empty of one who establishes the proofs of Allah so that His proofs ans signs never cease. They are the fewest in number, but the greatest in rank before Allah. Through them Allah preserves His proofs until they bequeath it to those like them (before passing on) and plant it firmly in their hearts. By them knowledge has taken by assault the reality of things, so that they found easy what those given to comfort found hard, and found intimacy in what the ignorant found desolate. They accompanied the world with bodies whose spirits were attached to the highest regard. Ah, ah! How one yearns to see them!"Imam al-Nawawi narrated a remarkable patrolinear chain for a hadith going back to `Ali: "Among the best of the narrations of the type 'sons from fathers' is that of al-Khatib with a chain going back to `Abd al-Wahhab ibn `Abd al-`Aziz ibn al-Harith ibn Asad ibn al-Layth ibn Sulayman ibn al-Aswad ibn Sufyan ibn Yazid ibn Akina al-Tamimi who said: I heard my father (Yazid) say: I heard my father (Sufyan) say: I heard my father (al-Aswad) say: I heard my father (Sulayman) say: I heard my father (al-Layth) say: I heard my father (Asad) say: I heard my father (al-Harith) say: I heard my father (`Abd al-`Aziz) say: I heard my father (`Abd al-Wahhab) say: I heard `Ali ibn Abi Talib say: 'The compassionate (al-hannân) is he who comes to the one who shunned him. The granter of favor (al-mannân) is he who extends the favor before he is asked for it."


Who is Shafii explain in brief?

Muhammad ibn Idris ibn al-`Abbas, al-Imam al-Shafi`i, Abu `Abd Allah al-Shafi`i al-Hijazi al-Qurashi al-Hashimi al-Muttalibi (d. 204), the offspring of the House of the Prophet, the peerless one of the great mujtahid imams and jurisprudent par excellence, the scrupulously pious ascetic and Friend of Allah, he laid down the foundations of fiqh in his Risala, which he said he revised and re-read four hundred times, then said: "Only Allah's Book is perfect and free from error."He is the cousin of the Prophet û Allah's blessings and peace upon him û descending from al-Muttalib who is the brother of Hashim, `Abd al-Muttalib's father. Someone praised the Banu Hashim in front of the Prophet, whereby he interlaced the fingers of his two hands and said: "We and they are but one and the same thing." Al-Nawawi listed three peculiar merits of al-Shafi`i: his sharing the Prophet's lineage at the level of their common ancestor `Abd Manaf; his birth in the Holy Land of Palestine and upbringing in Mecca; and his education at the hands of superlative scholars together with his own superlative intelligence and knowledge of the Arabic language. To this Ibn Hajar added two more: the hadith of the Prophet, "O Allah! Guide Quraysh, for the science of the scholar that comes from them will encompass the earth. O Allah! You have let the first of them taste bitterness, so let the latter of them taste reward." Another hadith of the Prophet says: "Truly, Allah shall send forth for this Community, at the onset of every hundred years, someone who will renew their Religion for them." The scholars agreed, among them Abu Qilaba (d. 276) and Imam Ahmad, that the first narration signified al-Shafi`i, and the second signified `Umar ibn `Abd al-`Aziz and then al-Shafi`i.He was born in Ghazza or `Asqalan in 150, the year of Abu Hanifa's death, and moved to Mecca at the age of two, following his father's death, where he grew up. He was early a skillful archer, then he took to learning language and poetry until he gave himself to fiqh, beginning with hadith. He memorized the Qur'an at age seven, then Malik's Muwatta' at age ten, at which time his teacher would deputize him to teach in his absence. At age thirteen he went to see Malik, who was impressed by his memory and intelligence.Malik ibn Anas and Muhammad ibn al-Hasan al-Shaybani were among his most prominent teachers and he took position against both of them in fiqh. Al-Shafi`i said: "From Muhammad ibn al-Hasan I wrote a camel-load." Al-Hakim narrated from `Abd Allah ibn `Abd al-Hakam: "Al-Shafi`i never ceased to speak according to Malik's position and he would say: 'We do not differ from him other than in the way of his companions,' until some young men spoke unbecomingly at length behind his back, whereupon al-Shafi`i resolved to put his differences with Malik in writing. Otherwise, his whole life he would say, whenever asked something: 'This is what the Teacher said' û hâdha qawl al-ustadh û meaning Malik."Like Abu Hanifa and al-Bukhari, he recited the entire Qur'an each day at prayer, and twice a day in the month of Ramadan.Al-Muzani said: "I never saw one more handsome of face than al-Shafi`i. If he grasped his beard it would not exceed his fist." Ibn Rahuyah described him in Mecca as wearing bright white clothes with an intensely black beard. Al-Za`farani said that when he was in Baghdad in the year 195 he dyed his beard with henna.Abu `Ubayd al-Qasim ibn Sallam said: "If the intelligence of an entire nation was brought together he would have encompassed it." Similarly, al-Muzani said: "I have been looking into al-Shafi`i's Risala for fifty years, and I do not recall a single time I looked at it without learning some new benefit."Al-Sakhawi in the introduction to his al-Jawahir WA al-Durar and others narrate that someone criticized Ahmad ibn Hanbal for attending the fiqh sessions of al-Shafi`i and leaving the hadith sessions of Sufyan ibn `Uyayna. Ahmad replied: "Keep quiet! If you miss a hadith with a shorter chain you can find it elsewhere with a longer chain and it will not harm you. But if you do not have the reasoning of this man [al-Shafi`i], I fear you will never be able to find it elsewhere." Ahmad is also related by his students Abu Talib and Humayd ibn Zanjuyah to say: "I never saw anyone adhere more to hadith than al-Shafi`i. No-one preceded him in writing down the hadith in a book." The meaning of this is that al-Shafi`i possessed the understanding of hadith after which Ahmad sought, as evidenced by the latter's statement: "How rare is fiqh among the scholars of hadith!" This is a reference to the hadith: "It may be one carries understanding (fiqh)without being a person of understanding (faqîh)." Sufyan himself would defer to al-Shafi`i in matters of tafsîr and fatwa. Yunus ibn Abi Ya`la said: "Whenever al-Shafi`i went into tafsîr, it was as if he had witnessed the revelation." Ahmad ibn Hanbal also said: "Not one of the scholars of hadith touched an inkwell nor a pen except he owed a huge debt to al-Shafi`i."Al-Shafi`i was known for his peculiar strength in Arabic language, poetry, and philology. Bayhaqi narrated:[From Ibn Hisham:] I was al-Shafi`i's sitting-companion for a long time, and I never heard him use except a word which, carefully considered, one would not find (in its context) a better word in the entire Arabic language. . . . Al-Shafi`i's discourse, in relation to language, is a proof in itself.[From al-Hasan ibn Muhammad al-Za`farani:] A group of bedouins used to frequent al-Shafi`i's gathering with us and sit in a corner. One day I asked their leader: "You are not interested in scholarship; why do you keep coming to sit with us?" They said: "We come to hear al-Shafi`i's language."Al-Shafi`i trod the path of the Salaf in avoiding any interpretation of the verses and narrations pertaining to the divine attributes. He practiced "relegation of the meaning" (tafwîd al-mi`na) to a higher source, as established in his saying: "I leave the meaning of the verses of the Attributes to Allah, and I leave the meaning of the hadiths of the attributes to Allah's Messenger." At the same time, rare instances of interpretation are recorded from him. Thus al-Bayhaqi relates that al-Muzani reported from al-Shafi`i the following commentary on the verse: "To Allah belong the East and the West, and wheresoever you turn, there is Allah's face (wajh)" (2:115): "It means - and Allah knows best - thither is the bearing (wajh) towards which Allah has directed you." Al-Hakkari (d. 486) related in his book `Aqida al-Shafi`i that the latter said: "We affirm those attributes, and we negate from them likeness between them and creation (al-tashbîh), just as He negated it from Himself when He said: 'There is nothing whatsoever like unto Him'(42:11)."Al-Shafi`i's hatred of dialectic theology (kalâm) was based on his extreme caution against errors which bear heavy consequences as they induce one into false beliefs. Among his sayings concerning this: "It is better for a scholar of knowledge to give a fatwa after which he is said to be wrong than to theologize and then be said to be a heretic (zindîq). I hate nothing more than theology and theologians." Dhahabi comments: "This indicates that Abu `Abd Allah's position concerning error in the principles of the Religion (al-usûl) is that it is not the same as error in the course of scholarly exertion in the branches." The reason is that in belief and doctrine neither ijtihâd nor divergences are permitted. In this respect al-Shafi`i said: "It cannot be asked 'Why?' concerning the principles, nor 'How?'" Yet al-Shafi`i did not completely close the door to the use of kalâm in defense of the Sunna, as shown below and in the notice on Ahmad ibn Hanbal.Yunus ibn Abi Ya`la narrated that al-Shafi`i defined the "principles" as: "The Qur'an, the Sunna, analogy (al-qiyâs), and consensus (al-ijmâ`)"; he defined the latter to mean: "The adherence of the Congregation (jamâ`a) of the Muslims to the conclusions of a given ruling pertaining to what is permitted and what is forbidden after the passing of the Prophet, blessings and peace be upon him."Al-Shafi`i did not close the door on the right use of kalâm as is clear from Ibn Abi Hatim's narration from al-Rabi` of his words: "If I wished, I could produce a book against each one of those who deviated, but dialectic theology is none of my business, and I would not like to be attributed any part in it." Similar to it is his advice to his student al-Muzani: "Take proofs from creation about the Creator, and do not burden yourself with the knowledge of what your mind did not reach." Ibn Abi Hatim himself spoke similarly when he was told of Ibn Khuzayma's unsuccessful attempt at kalâm: "It is preferable not to meddle with what we did not learn." Note that al-Shafi`i also spoke of his wish not to have a single letter out of all his works attributed to him, regardless of topic.Al-Shafi`i's attitude towards tasawwuf was as strict as with kalâm, and he both praised it and denigrated its abuse at the hands of its corrupters. In criticism of the latter he said: "No-one becomes a Sufi in the morning except he ends up a dolt by noon" while on the other hand he declared in his Diwan: "Be at the same time a faqîh and a Sufi." In Mecca al-Shafi`i was the student of Fudayl ibn `Iyad. Imam al-Nawawi in his Bustan al-`Arifin fi al-Zuhd WA al-Tasawwuf ("The Garden of the Gnostics in Asceticism and Tasawwuf") narrated from al-Shafi`i the saying: "Only the sincere one (al-mukhlis)can recognize self-display (al-riyâ')." Al-Nawawi comments: "This means that it is impossible to know the reality of self-display and see its hidden shades except for one who resolutely seeks (arâda) sincerity. Such a one strives for a long time, searching, meditating, examining at length within himself until he knows, or knows something of what self-display is. This does not happen for everyone. Indeed, this happens only with special ones (al-khawâss). But for a given individual to claim that he knows what self-diplay is, this is real ignorance on his part."Al-Shafi`i deferred primacy in the foundations of fiqh to Imam Abu Hanifa with his famous statement: "People are all the children of Abu Hanifa in fiqh." Ibn Hajar al-Haytami mentioned in the thirty-fifth chapter of his book on Imam Abu Hanifa entitled al-Khayrat al-Hisan: "When Imam al-Shafi`i was in Baghdad, he would visit the grave of Imam Abu Hanifa, greet him, and then ask Allah for the fulfillment of his need through his means."Two schools of legal thought or madhahib are actually attributed to al-Shafi`i, englobing his writings and legal opinions (fatâwa). These two schools are known in the terminology of jurists as "The Old" (al-qadîm) and "The New" (al-jadîd), corresponding respectively to his stays in Iraq and Egypt. The most prominent transmitters of the New among al-Shafi`i's students are al-Buwayti, al-Muzani, al-Rabi` al-Muradi, and al-Bulqini, in Kitab al-Umm ("The Motherbook"). The most prominent transmitters of the Old are Ahmad ibn Hanbal, al-Karabisi, al-Za`farani, and Abu Thawr, in Kitab al-Hujja ("Book of the Proof"). What is presently known as the Shafi`i position refers to the New except in approximately twenty-two questions, in which Shafi`i scholars and muftis have retained the positions of the Old.Al-Subki related that the Shafi`i scholars considered al-Rabi`s narration from al-Shafi`i sounder from the viewpoint of transmission, while they considered al-Muzani's sounder from the viewpoint of fiqh, although both were established hadith masters. Al-Shafi`i said to al-Rabi`: "How I love you!" and another time: "O Rabi`! If I could feed you the Science I would feed it to you." Al-Qaffal al-Shashi in his Fatawa relates that al-Rabi` was slow in his understanding, and that al-Shafi`i once repeated an explanation forty times for him in a gathering, yet he did not understand it then got up and left in embarrassment. Later, al-Shafi`i called him in private and resumed explaining it to him until he understood. This shows the accuracy of Ibn Rahuyah's statement: "I consider the best part of me the time when I fully understand al-Shafi`i's discourse."Al-Shafi`i took the verse "Or if you have touched women"(4:43) literally, and considered that contact between the sexes, even accidental, nullified ablution. This is also the position of Ibn Mas`ud, Ibn `Umar, al-Sha`bi, al-Nakha`i, al-Zuhri, and al-Awza`i, which is confirmed by Ibn `Umar's report: "Whoever kisses or touches his wife with his hand must renew his wudû'." It is authentic and related in numerous places including Malik's Muwatta'. Al-Shafi`i said: "Something similar has reached us from Ibn Mas`ud." They all read the above verse literally, without interpreting "touch" to mean "sexual intercourse" as do the Hanafis, or "touch with pleasure" as do the Malikis.A major contribution of al-Shafi`i in the foundations of the Law was his division of innovation (al-bid`a) into good and bad on the basis of `Umar's words about the tarâwih or congregational supererogatory night prayers in the month of Ramadan: "What a fine innovation this is!" Harmala narrated that al-Shafi`i concluded: "Therefore, whatever innovation conforms to the Sunna is approved (mahmûd), and whatever opposes it is abominable (madhmûm)." Agreement formed in the Four Schools around his division, as illustrated by the endorsement of some major later authorities in each school. Among the Hanafis: Ibn `Abidin, al-Turkumani, and al-Tahanawi; among the Malikis: al-Turtushi, Ibn al-Hajj, and al-Shatibi; consensus among the Shafi`is; and reluctant acceptance among later Hanbalis, who altered al-Shafi`i's terminology to read "lexical innovation" (bid`a lughawiyya) and "legal innovation" (bid`a shar`iyya), respectively û although inaccurately û matching Shafi`i's "approved" and "abominable".Among al-Shafi`i's other notable positions: Al-Muzani said: "I never saw any of the scholars make something obligatory on behalf of the Prophet as much as al-Shafi`i in his books, and this was due to his high remembrance of the Prophet. He said in the Old School: 'Supplication ends with the invocation of blessings on the Prophet, and its end is but by means of it.'" Al-Karabisi said: "I heard al-Shafi`i say that he disliked for someone to say 'the Messenger' (al-Rasûl), but that he should say 'Allah's Messenger' (Rasûl Allah) out of veneration (ta`zîm) for him."Among al-Shafi`i's other sayings:"The study of hadith is better than supererogatory prayer, and the pursuit of knowledge is better than supererogatory prayer." Ibn `Abd al-Barr in Kitab al-`Ilm listed the many hadiths of the Prophet on the superior merit of knowledge. However, al-Shafi`i by this saying meant the essence and purpose of knowledge, not knowledge for its own sake which leads to Satanic pride. The latter is widely available while true knowledge is the knowledge that leads to godwariness (taqwa). This is confirmed by al-Shafi`i's saying: "Knowledge is what benefits. Knowledge is not what one has memorized." This is a corrective for those content to define knowledge as "the knowledge of the proof" (ma`rifa al-dalîl). "He gives wisdom to whomever He will, and whoever receives wisdom receives immense good." (2:269)"You [the scholars of hadith] are the pharmacists but we [the jurists] are the physicians." This was explained by `Ali al-Qari in his book Mu`taqad Abi Hanifa al-Imam (p. 42): "The early scholars said: The hadith scholar without knowledge of fiqhis like a seller of drugs who is no physician: he has them but he does not know what to do with them; and the fiqh scholar without knowledge of hadith is like a physician without drugs: he knows what constitutes a remedy, but does not dispose of it.""Malik was asked about kalâm and [the Science of] Oneness (tawhîd) and he said: 'It is inconceivable that the Prophet should teach his Community hygiene and not teach them about Oneness! And Oneness is exactly what the Prophet said: 'I was ordered to fight people until they say 'There is no God but Allah.' So, whatever makes blood and property untouchable û that is the reality of Oneness (haqîqa al-tawhîd).'" This is a proof from the Salaf against those who, in later times, innovated sub-divisions for tawhîd or legislated that their own understanding of Allah's Attributes was a precondition for the declaration of Oneness. Al-Halimi said: "In this hadith there is explicit proof that that declaration (lâ ilâha illallâh)suffices to extirpate oneself from all the different kinds of disbelief in Allah Almighty.""Satiation weighs down the body, hardens the heart, does away with sagacity, brings on sleep, and weakens one from worship." This is similar to the definition of tasawwuf as "hunger" (al-jû`) given by some of the early masters, who acquired hunger as a permanent attribute and were called "hungerers" (jû`iyyûn). A notable example is al-Qasim ibn `Uthman al-`Abdi al-Dimashqi al-Ju`i (d. 248), whom al-Dhahabi describes as "the Imam, the exemplar, the wali, the muhaddith, the shaykh of the Sufis and the friend of Ahmad ibn al-Hawari.""I never swore by Allah û neither truthfully nor deceptively." This is similar to the saying of the Sufi master Sahl ibn `Abd Allah al-Tustari narrated by al-Dhahabi: "Among the manners of the truthful saints (al-siddîqîn) is that they never swear by Allah, nor commit backbiting, nor does backbiting take place around them, nor do they eat to satiation, if they promise they are true to their word, and they never speak in jest."Al-Buwayti asked: "Should I pray behind the Rafidi?" Al-Shafi`i said: "Do not pray behind the Rafidi, nor behind the Qadari, nor behind the Murji'." Al-Buwayti said: "Define them for us." He replied: "Whoever says 'Belief consists only in speech' is a Murji', and whoever says 'Abu Bakr and `Umar are not Imams' is a Rafidi, and whoever attributes destiny to himself is a Qadari."Abu Hatim narrated from Harmala that al-Shafi`i said: "The Caliphs (al-khulafâ') are five: Abu Bakr, `Umar, `Uthman, `Ali, and `Umar ibn `Abd al-`Aziz." In his Diwan he named them "leaders of their people, by whose guidance one obtains guidance," and declaimed of the Family of the Prophet:The Family of the Prophet are my intermediary to him! (wasîlatî)Through them I hope to be given my record with the right hand.and:O Family of Allah's Messenger! To love you is an obligationWhich Allah ordained and revealed in the Qur'an.It is enough proof of your immense glory thatWhoever invokes not blessings upon you, his prayer is invalid.Ibn Hajar said that the first to write a biography of al-Shafi`i was Dawud al-Zahiri (d. 275). Al-Nawawi in Tahdhib al-Asma' WA al-Lughat (1:44) mentioned that the best biography of al-Shafi`i was al-Bayhaqi's for its sound chains of transmission. Ibn Hajar summarized it and added to it al-Shafi`i's Musnadin his Tawali al-Ta'sis fi Ma`ali Ibn Idris.In the introduction of his compendium of Shafi`i fiqhentitled al-Majmu` al-Nawawi mentions that al-Shafi`i used a walking stick for which he was asked: "Why do you carry a stick when you are neither old nor ailing?" He replied: "To remember I am only a traveller in this world."


What Muslim technologies influenced other civilizations?

Chemical industriesJabir ibn Hayyan (Geber), the "father of chemistry", invented the alembic still and many chemicals, including distilled alcohol, and established the perfume industry. Muhammad ibn Zakariya ar-Razi (Rhazes) isolated many chemical substances, produced many medications, and described many laboratory apparatus.Laboratory setup for steam distillation, invented by Avicenna in the 11th century.Aqua regia was first isolated by Geber.Hydrochloric acid, a mineral acid, was first isolated by Geber.Nitric acid, a mineral acid, was first isolated by Geber.Sulfuric acid, a mineral acid, was first isolated by Geber.Arsenic, a chemical element, was first isolated by Geber in the 8th century.Coloured stained glass windows in the Nasir al-Mulk mosque in Shiraz, Iran.See also: Alchemy and chemistry in IslamEarly forms of distillation were known to the Babylonians, Greeks and Egyptians since ancient times, but it was Muslim chemists who first invented pure distillation processes which could fully purify chemical substances. They also developed several different variations of distillation (such as dry distillation, destructive distillation and steam distillation) and introduced new distillation aparatus (such as the alembic, still, and retort), and invented a variety of new chemical processes and over 9,000 chemical substances.[2]Will Durant wrote in The Story of Civilization IV: The Age of Faith:"Chemistry as a science was almost created by the Moslems; for in this field, where the Greeks (so far as we know) were confined to industrial experience and vague hypothesis, the Saracens introduced precise observation, controlled experiment, and careful records. They invented and named the alembic (al-anbiq), chemically analyzed innumerable substances, composed lapidaries, distinguished alkalis and acids, investigated their affinities, studied and manufactured hundreds of drugs. Alchemy, which the Moslems inherited from Egypt, contributed to chemistry by a thousand incidental discoveries, and by its method, which was the most scientific of all medieval operations."[3]Robert Briffault wrote in The Making of Humanity:"Chemistry, the rudiments of which arose in the processes employed by Egyptian metallurgists and jewellers combining metals into various alloys and 'tinting' them to resemble gold, processes long preserved as a secret monopoly of the priestly colleges, and clad in the usual mystic formulas, developed in the hands of the Arabs into a widespread, organized passion for research which led them to the invention of distillation, sublimation, filtration, to the discovery of alcohol, of nitric and sulphuric acids (the only acid known to the ancients was vinegar), of the alkalis, of the salts of mercury, of antimony and bismuth, and laid the basis of all subsequent chemistry and physical research."[4][edit] Chemical processesThe following chemical processes were invented by Muslim chemists: Assation (or roasting), cocotion (or digestion), ceration, lavage, solution, mixture, and fixation.[5]Calcination (al-tashwiya): Invented by Geber.[6][7]Crystallization (al-tabalwur): Invented by Geber.[8]Distillation, pure (al-taqtir): Geber (Jabir ibn Hayyan) was the first to fully purify chemical substances through distillation, using the alembic, in the 8th century.[4]Destructive distillation: Invented by Muslim chemists in the 8th century to produce tar from petroleum.[9]Dry distillationFiltration (al-tarshih): Invented by Geber.[4]Liquefaction, purification, oxidisation, and evaporation (tabkhir): Invented by Geber.[10]Solution (al-tahlil), sublimation(al-tas'id), amalgamation (al-talghim), ceration (al-tashmi), and a method of converting a substance into a thick paste or fusible solid.[6]Steam distillation: Invented by Avicenna in the early 11th century for the purpose of producing essential oils.[11][citation needed]Water purification[edit] Chemical substancesArsenic, alkali, alkali salt, borax, and pure sal ammoniac: Isolated by Geber (Jabir ibn Hayyan) in the 8th century.[7]Cheese glue and plated mail: Invented by Geber.[12]Derivative and artificial chemical substances: In the 10th century, Muhammad ibn Zakarīya Rāzi wrote that he and his Muslim predecessors (Calid, Geber and al-Kindi) invented the following derivative and artificial substances: lead(II) oxide (PbO), red lead (Pb3O4), tin(II) oxide(Isfidaj), copper acetate (Zaniar), copper(II) oxide (CuO), lead sulfide, zinc oxide, bismuth oxide, antimony oxide, iron rust, iron acetate, Daws (a contituent of steel), cinnabar (HgS), arsenic trioxide (As2O3), alkali (al-Qili), sodium hydroxide (caustic soda), and Qalimiya (anything that separates from metals during their purification).[13]Ethanol and pure ammonia: Isolated by Arabic chemists.[14]Lead carbonatic: Isolated by Geber.[15]Medicinal substances: Muslim chemists discovered 2,000 medicinal substances.[2]Potassium nitrate, pure: Isolated by Hasan al-Ramah in the 1270s.[7]Rose water: First produced by Muslim chemists in the medieval Islamic world through the distillation of roses, for use in the drinking and perfumery industries.[7]Sal nitrum: Isolated by Geber.[7]Acids Aqua regia: Isolated by Geber (Jabir ibn Hayyan) in the 8th century.[7]Carboxylic acids: Geber isolated Acetic acid from vinegar.[8][16] He is also credited with the discovery and isolation of Citric acid, the sour component of lemons and other unripe fruits.[8]Mineral acids: The mineral acids-nitric acid, sulfuric acid, and hydrochloric acid-were first isolated by Geber.[17] He originally referred to sulfuric acid as the oil of vitriol.[7][14][18]Organic acids: Geber isolated Uric acid.[10] He also isolated Tartaric acid from wine-making residues.[8]Elements Arsenic: Isolated by Geber in the 8th century.[15]Antimony: Isolated by Geber.[4][15][edit] Food and drinkCoffee: Produced by Khalid in Kaffa, Ethiopia, in the 9th century.[10]Confectionery: Due to advances in sugar production and the invention of sugar refineries, this led to the production of early confectioneries by the Arabs.[19]Distilled water and water purification: Purified by Muslim chemists.[14]Pure distilled alcohol and ethanol: First isolated by Al-Kindi (Alkindus) in the 9th century.[7][20] Ahmad Y Hassan wrote: "The distillation of wine and the properties of alcohol were known to Islamic chemists from the eighth century. The prohibition of wine in Islam did not mean that wine was not produced or consumed or that Arab alchemists did not subject it to their distillation processes. Jabir ibn Hayyan described a cooling technique which can be applied to the distillation of alcohol."[21]Restaurant and three-course meal: The earliest restaurants came into existence throughout the Islamic world from the 10th century, shortly before restaurants appeared in China in the 11th century. The Islamic world had "restaurants where one could purchase all sorts of prepared dishes." These restaurants were mentioned by Al-Muqaddasi (born 945) in the late 10th century.[22] Restaurants in medieval Islamic Spain served three-course meals, which was earlier introduced in the 9th century by Ziryab, who insisted that meals should be served in three separate courses consisting of soup, the main course, and dessert.[23]Rose water: See Chemical substances above.Sugar refinery: See Industrial milling below.[edit] Glass industryArtificial gemstone: Geber (d. 815) first described the production of high-quality coloured glass cut into artificial gemstones.[24][25]Artificial pearl and purification of pearls: In his Kitab al-Durra al-Maknuna (The Book of the Hidden Pearl), Jabir described the first recipes for the manufacture of artificial pearls and for the purification of pearls that were discoloured from the sea or from grease.[26]Coloured stained glass windows: Muslim architects in Southwest Asia were the first to produce stained glass windows using coloured glass rather than stone producing a stained glass-like effect, as was the case in early churches. In the 8th century, the Arab chemist Geber scientifically described 46 original recipes for producing high-purity coloured glass in Kitab al-Durra al-Maknuna (The Book of the Hidden Pearl), in addition to 12 recipes inserted by al-Marrakishi in a later edition of the book.[24][25]Concave, convex and spherical mirrors: Ibn al-Haytham (Alhazen) gave the earliest accurate descriptions of concave and convex mirrors in both cylindrical and spherical geometries,[27] and he also gave the earliest accurate description of spherical mirrors.[28]Dying and artificial colouring of gemstones and pearls: In The Book of the Hidden Pearl, Geber described the first recipes for the dying and artificial colouring of gemstones and pearls.[26]Glass factory: The first industrial complex for glass and pottery production was built in Ar-Raqqah, Syria, in the 8th century. Extensive experimentation was carried out at the complex, which was two kilometres in length, and a variety of innovative high-purity glass were developed there. Two other similar complexes have also been discovered, and nearly three hundred new chemical recipes for glass are known to have been produced at all three sites.[29] The first glass factories were thus built by Muslim craftsmen in the Islamic world. The first glass factories in Europe were later built in the 11th century by Egyptian craftsmen in Corinth, Greece.[17]Quartz glass and Silica glass: The production of glass from stone (including quartz) and sand, was pioneered by Abbas Ibn Firnas in the 9th century.[30]Parabolic mirror: Invented by Ibn Sahl in the 10th century.[31] These observations were repeated by Ibn al-Haytham in his Book of Optics (1021).[28][edit] Military technologySee also: Alchemy and chemistry in Islam A picture of a 15th century Granadian siege cannon from the book Al-izz wal rifa'a.The Ottoman Janissary corps were using matchlock muskets since the 1440s. They are depicted battling the Knights Hospitaller in this 1522 painting.Damascus steel: One of the most famous steels produced in the medieval Near East was Damascus steel used for swordmaking, and mostly produced in Damascus, Syria, in the period from 900 to 1750. This was produced using the crucible steel method, based on the earlier Indian wootz steel. This process was further refined in the Middle East using locally produced steels. The process allowed carbides to precipitate out as micro particles arranged in sheets or bands within the body of a blade. The carbides are far harder than the surrounding low carbon steel, allowing the swordsmith to make an edge which would cut hard materials with the precipitated carbides, while the bands of softer steel allowed the sword as a whole to remain tough and flexible. A team of researchers based at the Technical University of Dresden that uses x-rays and electron microscopy to examine Damascus steel discovered the presence of cementite nanowires[32] and carbon nanotubes.[33] Peter Paufler, a member of the Dresden team, says that these nanostructures give Damascus steel its distinctive properties[34] and are a result of the forging process.[34][35]Dissolved talc: Egyptian soldiers at the Battle of Ain Jalut in 1260 were the first to smear dissolved talc (from Arabic talq) on their hands, as forms of fire protection from gunpowder.[36]Fireproof clothing: Asbestos may have possibly been used as a form of fire protection by the ancient Chinese and Greeks. However, it was Egyptian soldiers at the Battle of Ain Jalut in 1260 who were the first to wear fireproof clothing to protect themselves from gunpowder fires as well as chemicals in gunpowder warfare. Their fireroof protective clothing consisted of a silk tunic (still worn by Formula 1 drivers underneath their Nomex fire suits), aketon (from the Arabic al-qutn "the cotton"), and mainly a woolen overtunic that protects against fires and chemical weapons], similar to the clothing worn by modern soldiers for protection against biological, chemical and nuclear weapons. Due to the effectiveness of their fireproof clothing, the Egyptian soldiers were able to attach gunpowder cartridges and incendiary devices to their clothing.Gunpowder cartridge: Gunpowder cartridges were first employed by the Egyptians, for use in their fire lances and hand cannons against the Mongols at the Battle of Ain Jalut in 1260.[36]Hand cannon, handgun, and small arms: The first portable hand cannons (midfa) loaded with explosive gunpowder, the first example of a handgun and portable firearm, were used by the Egyptians to repel the Mongols at the Battle of Ain Jalut in 1260, and again in 1304. The gunpowder compositions used for the cannons at these battles were later described in several manuscripts in the early 14th century. According to Shams al-Din Muhammad (d. 1327), the cannons had an explosive gunpowder composition (74% saltpetre, 11% sulfur, 15% carbon) almost identical to the ideal compositions for explosive gunpowder used in modern times (75% saltpetre, 10% sulfur, 15% carbon).[36]Matchlock: The Janissary corps of the Ottoman army were using matchlock muskets as early as the 1440s.[37] The first dated illustration of a matchlock mechanism in Europe dates to 1475.Purified potassium nitrate: Muslim chemists were the first to purify potassium nitrate (saltpetre; natrun or barud in Arabic) to the weapons-grade purity for use in gunpowder, as potassium nitrate needs to be purified to be used effectively. This purification process was first described by Ibn Bakhtawayh in his al-Muqaddimat in 1029. The first complete purification process for potassium nitrate is described in 1270 by the Arab chemist and engineer Hasan al-Rammah of Syria in his book al-Furusiyya WA al-Manasib al-Harbiyya ('The Book of Military Horsemanship and Ingenious War Devices', a.k.a. the Treatise on Horsemanship and Stratagems of War). He first described the use of potassium carbonate (in the form of wood ashes) to remove calcium and magnesium salts from the potassium nitrate.[36][38] Hasan al-Rammah also describes the purifying of saltpetre using the chemical processes of solution and crystallization, and this was the first clear method for the purification of saltpetre.[39] Bert S. Hall,[40] however, disputes the efficacy of al-Rammah's formula for the purification of potassium nitrate.[edit] Oil industryEssential oil: Invented by Abū Alī ibn Sīnā (Avicenna) in the 11th century.[11]Kerosene and kerosene lamp: Invented by Muhammad ibn Zakarīya Rāzi in the 9th century.[41]Oil field, petroleum industry, naphtha, and tar: An early petroleum industry was established in the 8th century, when the streets of Baghdad were paved with tar, derived from petroleum through destructive distillation. In the 9th century, oil fields were first exploited in the area around modern Baku, Azerbaijan, to produce naphtha. These fields were described by al-Masudi in the 10th century, and by Marco Polo in the 13th century, who described the output of its oil wells as hundreds of shiploads.[9]Petrol: Muslim chemists were the first to produce petrol from crude oil.[42][edit] PotteryMain article: Islamic pottery Tin-glazed Hispano-Moresque ware with lusterware decoration, from Spain circa 1475.Albarello: An albarello is a type of maiolica earthenware jar originally designed to hold apothecaries' ointments and dry drugs. The development of this type of pharmacy jar had its roots in the Islamic Middle East. Brought to Italy by Hispano-Moresque traders, the earliest Italian examples were produced in Florence in the 15th century.Hispano-Moresque ware: This was a style of Islamic pottery created in Islamic Spain, after the Moors had introduced two ceramic techniques to Europe: glazing with an opaque white tin-glaze, and painting in metallic lusters. Hispano-Moresque ware was distinguished from the pottery of Christendom by the Islamic character of it decoration.[43]Lusterware: Invented by Geber, who applied it to ceramic glazes in the 8th century.[44] The technique soon became popular in Persia from the 9th century, and lusterware was later produced in Egypt during the Fatimid caliphate in the 10th-12th centuries. While the production of lusterware continued in the Middle East, it spread to Europe-first to Al-Andalus, notably at Malaga, and then to Italy, where it was used to enhance maiolica.Pottery factory: The first industrial complex for glass and pottery production was built in Ar-Raqqah, Syria, in the 8th century. Extensive experimentation was carried out at the complex, which was two kilometres in length. Two other similar complexes have also been discovered.[29]Stonepaste ceramic: Invented in 9th-century Iraq,[45] it was a vitreous or semivitreous ceramic ware of fine texture, made primarily from non-refactory fire clay.[46]Tin-glazing: The tin-glazing of ceramics was invented by Muslim potters in 8th-century Basra, Iraq. Tin-opacified glazing was one of the earliest new technologies developed by the Islamic potters. The first examples of this technique can be found as blue-painted ware in 8th-century Basra.[47]Tin-glazed pottery: The earliest tin-glazed pottery appears to have been made in Iraq in the 9th century, the oldest fragments having been excavated during the First World War from the palace of Samarra about fifty miles north of Baghdad.[48] From there, it spread to Egypt, Persia and Spain, before reaching Italy in the Renaissance, Holland in the 16th century, and England, France and other European countries shortly after.[edit] Civil engineeringThe interiors of the Alhambra in Spain are decorated with arabesque designs. The minaret is a distinct feature of Islamic architecture. The spiralling minaret located at the Great Mosque of Samarra, Iraq built in 852, is one of the oldest.At 72.5 meters, the Qutab Minar was the tallest minaret until the 20th century, and remains the tallest brick and stone minaret in the world.The tallest minaret is currently the one at Hassan II Mosque, at 210 metres (689 ft) tall, pictured above.An illustration of patterned Girih tiles, found in Islamic architecture dating back over five centuries ago. These featured the first quasicrystal patterns and self-similar fractal quasicrystalline tilings.The norias in Hama on the Orontes River in Syria. The flywheel was first employed in a noria by Ibn Bassal in the 11th century.The first windmills were built in the Islamic world and introduced to Europe through Spain.During the Muslim Agricultural Revolution, the early Muslim Arab Empire was ahead of its time regarding domestic water systems such as water cleaning systems and advanced water transportation systems resulting in better agriculture, something that helped in issues related to Islamic hygienical jurisprudence.[49] Al-Jazari invented a variety of machines for raising water in 1206,[50] as well as water mills and water wheels with cams on their axle used to operate automata in the late 12th century.[51]Kerosene lamp, and litter collection facilities: Cordoba had the first facilities and waste containers for litter collection.[52] The first kerosene lamp was invented by Muhammad ibn Zakarīya Rāzi in the 9th century.[41]Surveying instruments: Muslim engineers invented a variety of surveying instruments for accurate levelling, including a wooden board with a plumb line and two hooks, an equilateral triangle with a plumb line and two hooks, and a "reed level". They also invented a rotating alidade used for accurate alignment, and a surveying astrolabe used for alignment, measuring angles, triangulation, finding the width of a river, and the distance between two points separated by an impassable obstruction.[53]Tar roads and pavements: Tar was a vital component of the first sealed tarmac roads. The streets of Baghdad were the first to be paved with tar from the 8th century AD. Tar was derived from petroleum, accessed from oil fields in the region, through the chemical process of destructive distillation.[9]Ventillator: The first ventillators were invented in Islamic Egypt and were widely used in many houses throughout Cairo during the Middle Ages. These ventillators were later described in detail by Abd al-Latif al-Baghdadi in 1200, who reported that almost every house in Cairo has a ventillator, and that they cost anywhere from 1 to 500 dinars depending on their sizes and shapes. Most ventillators in the city were oriented towards the Qibla (the direction of Mecca), as was the city in general.[54][edit] ArchitectureAcequia: A community operated waterway used in Spain and former Spanish colonies in the Americas for irrigation, they were first introduced by the Moors in Al-Andalus before the 13th century.[17]Arabesque: An elaborative application of repeating geometric forms often found decorating the walls of mosques. Geometric artwork in the form of the Arabesque was not used in the Middle East or Mediterranean Basin until the Islamic Golden Age. Euclidean geometry as expounded on by Al-Abbās ibn Said al-Jawharī (ca. 800-860) in his Commentary on Euclid's Elements, the trigonometry of Aryabhata and Brahmagupta as elaborated on by Muhammad ibn Mūsā al-Khwārizmī (ca. 780-850), and the development of spherical geometry[55] by Abū al-Wafā' al-Būzjānī (940-998) and spherical trigonometry by Al-Jayyani (989-1079)[56] for determining the Qibla (direction to Mecca) and times of Salah prayers and Ramadan,[55] all served as an impetus for the art form that was to become the Arabesque.Bridge dam: The bridge dam was used to power a water wheel working a water-raising mechanism. The first was built in Dezful, Iran, which could raise 50 cubits of water for the water supply to all houses in the town. Similar bridge dams later appeared in other parts of the Islamic world.[57]Central heating through underfloor pipes: The hypocaust heating system used by the Romans continued to be in use around the Mediterranean region during late Antiquity and by the Umayyad caliphate. By the 12th century, Muslim engineers in Syria introduced an improved central heating system, where heat travelled through underfloor pipes from the furnace room, rather than through a hypocaust. This central heating system was widely used in bath-houses throughout the medieval Islamic world.[58]Cobwork: The earliest appearance of cobwork (tabya) dates back to the Maghreb and Al-Andalus in the 11th century, and was first described in detail by Ibn Khaldun in the 14th century, who regarded it as a characteristically Muslim practice. Cobwork later spread to other parts of Europe from the 12th century onwards.[59]Geared and hydropowered water supply system: Al-Jazari developed the earliest water supply system to be driven by gears and hydropower, which was built in 13th century Damascus to supply water to its mosques and Bimaristan hospitals. The system had water from a lake turn a scoop-wheel and a system of gears which transported jars of water up to a water channel that led to mosques and hospitals in the city.[60]Girih tiles, quasicrystal pattern, and self-similar fractal quasicrystalline tiling: Geometrical quasicrystal patterns were first employed in the girih tiles found in medieval Islamic architecture dating back over five centuries ago. In 2007, Professor Peter Lu of Harvard University and Professor Paul Steinhardt of Princeton University published a paper in the journal Science suggesting that girih tilings possessed properties consistent with self-similar fractal quasicrystalline tilings such as the Penrose tilings, predating them by five centuries.[61][62]High-rise roof garden: The medieval Egyptian city of Fustat had a number of high-rise buildings which Nasir Khusraw in the early 11th century described as rising up to 14 stories, with roof gardens on the top storey complete with ox-drawn water wheels for irrigating them.[63]Minaret: The minaret is a distinctive architectural feature of Islamic architecture, especially mosques, dating back to the early centuries of Islam. Minarets are generally tall spires with onion-shaped crowns, usually either free standing or much taller than any surrounding support structure. The tallest minaret in pre-modern times was the Qutub Minar, which was 72.5 meters (237.9 ft) tall and was built in the 12th century, and it remains the tallest brick and stone minaret in the world. The tallest minaret in modern times is the one at Hassan II Mosque, which is 210 metres (689 ft) tall and was built in 1986.[edit] Industrial millingSee also: Muslim Agricultural Revolution A variety of industrial mills were active in the medieval Islamic world, including fulling mills, gristmills, hullers, paper mills, sawmills, stamp mills, steel mills, sugar mills, and windmills, many of which were original inventions by Muslim engineers. By the 11th century, every province throughout the Islamic world had these industrial mills in operation, from Al-Andalus and North Africa to the Middle East and Central Asia.[64] These advances made it possible for many industrial operations that were previously driven by manual labour in ancient times to be driven by machinery instead in the Islamic world. The transfer of these technologies to medieval Europe later laid the foundations for the Industrial Revolution in 18th century Europe.[65]Bridge mill: The bridge mill was a unique type of water mill that was built as part of the superstructure of a bridge. The earliest record of a bridge mill is from Cordoba, Spain in the 12th century.[66]Factory milling installation: The first factory milling installations were built by Muslim engineers throughout every city and urban community in the Islamic world. For example, the factory milling complex in 10th century Baghdad could produce 10 tonnes of flour] every day.[67] The first large milling installations in Europe were built in 12th century Islamic Spain.[68]Flywheel-driven noria: See Mechanical technology below.Fulling mill: The first references to fulling mills are reported in Persia from the 10th century. By the time of the Crusades in the 11th century, fulling mills were active throughout the Islamic world, from Islamic Spain and North Africa to Central Asia.[64]Geared and wind powered gristmills with trip hammers: The first geared gristmills[69] were invented by Muslim engineers in the Islamic world, and were used for grinding corn and other seeds to produce meals, and many other industrial uses such as fulling cloth, husking rice, papermaking, pulping sugarcane, and crushing metallic ores before extraction. Gristmills in the Islamic world were often made from both watermills and windmills. In order to adapt water wheels for gristmilling purposes, cams were used for raising and releasing trip hammers to fall on a material.[70] The first wind-powered gristmills driven by windmills were built in what are now Afghanistan, Pakistan and Iran in the 9th and 10th centuries.[68]Hydropowered forge and finery forge: The first forge to be driven by a hydropowered water mill rather than manual labour, also known as a finery forge, was invented in 12th century Islamic Spain.[68]Paper mill: Paper was introduced into the Muslim world by Chinese prisoners after the Battle of Talas. Muslims made several improvements to papermaking, mainly the use of hydropower rather than manual labour to produce paper, and they built the first paper mills in Baghdad, Iraq, as early as 794. Papermaking was transformed from an art into a major industry as a result.[71][72]Stamp mill: Stamp mills were first used by miners in Samarkand from as early as 973. They were used in medieval Persia for the purpose of crushing ore. By the 11th century, stamp mills were in widespread use throughout the Islamic world, from Islamic Spain and North Africa to Central Asia.[64]Sugar refinery: The first sugar refineries were built by Muslim engineers.[64] They were first driven by water mills, and then windmills from the 9th and 10th centuries in Afghanistan, Pakistan, and Iran.[68]Underground watermill: Other innovations that were unique to the Islamic world include the situation of watermills in the underground irrigation tunnels of a qanat and on the main canals of valley-floor irrigation systems.[68]Windmill: The first windmills were built in Sistan, Afghanistan, sometime between the 7th century and 9th century, as described by Muslim geographers. These were vertical axle windmills, which had long vertical driveshafts with rectangle shaped blades.[73] The first windmill may have been constructed as early as the time of the second Rashidun caliph Umar (634-644 AD), though some argue that this account may have been a 10th century amendment.[74] Made of six to twelve sails covered in reed matting or cloth material, these windmills were used to grind corn and draw up water, and used in the gristmilling and sugarcane industries.[70] The first horizontal windmills were built in what are now Afghanistan, Pakistan and Iran in the 9th and 10th centuries. They had a variety of uses, such as grinding grain, pumping water, and crushing sugar-cane.[68] A small primitive wind wheel operating an organ is described as early as the 1st century AD by Hero of Alexandria, marking probably the first instance of a wind powering machine in history.[75][76] Horizontal axle windmills of the type generally used today were developed in Northwestern Europe in the 1180s.[77][edit] CosmeticsA number of hygienic cosmetics were invented by Muslim chemists, cosmetologists and physicians.[78] Cosmetic dentistry and tooth bleaching: In his Al-Tasrif (c. 1000), Abulcasis described methods for strengthening the gums and introduced the method of tooth bleaching using tooth whiteners.[79]Bangs: In the 9th century, Ziryab introduced a new hairstyle for women in Al-Andalus: a "shorter, shaped cut, with bangs on the forehead and the ears uncovered."[80]Beauty parlour and cosmetology school: In the 9th century, Ziryab opened the first beauty parlour and "cosmetology school" for women near Alcázar, Al-Andalus."[80]Chemical depilatory for hair removal: In the 9th century, Ziryab taught women in Al-Andalus "the shaping of eyebrows and the use of depilatories for removing body hair".[80]Hair care and hair dye: In his Al-Tasrif (c. 1000), Abulcasis first described hair dyes for changing human hair color to blond or black hair, and hair care for correcting kinky or curly hair.[79] Dyestuff was also created by earlier Muslim chemists.[81]Lipstick, solid: In 1000 CE, the Andalusian Arab cosmetologist Abu al-Qasim al-Zahrawi (Abulcasis) invented solid lipsticks, which were perfumed stocks rolled and pressed in special molds, and he described them in his Al-Tasrif.[79]Pomade: Produced by Arabs.[14][edit] HygieneHand cream and lotion, and suntan lotion[disambiguation needed]: In his Al-Tasrif (c. 1000), Abulcasis described the first hand creams and lotions, and the first early suntan lotions, describing their ingredients and benefits in depth.[79]Toothpaste, functional and pleasant: In the 9th century, the Persian musician and fashion designer Ziryab is known to have invented a type of toothpaste, which he popularized throughout Islamic Spain.[82] The exact ingredients of this toothpaste are not currently known,[80] but unlike the earlier Egyptian and Roman toothpastes, Ziryab's toothpaste was reported to have been both "functional and pleasant to taste."[82] In circa 1000, Abulcasis recommended a toothpaste made from cinnamon, nutmeg, cardamom and coriander leaves, as a remedy for bad breath resulting from eating garlic or onions.[79][edit] PerfumeryPerfume usage was recorded in the Arabian Peninsula since the 7th century, and Muslims made many advances in perfumery in the proceeding centuries. This included the extraction of numerous fragrances, as well as the cheap mass-production of incenses. Muslim scientists such as Al-Kindi elaborated a vast number of recipes for a wide range of perfumes, cosmetics and pharmaceuticals. Perfume industry: Established by Geber (Jabir) (b. 722, Iraq) and Al-Kindi (b. 801, Iraq).[83] Jabir developed many techniques, including distillation, evaporation and filtration, which enabled the collection of the odour of plants into a vapour that could be collected in the form of water or oil.[83] Al-Kindi carried out extensive research and experiments in combining various plants and other sources to produce a variety of scent products.Camphor: In the 9th century, the Arab chemist Al-Kindi (Alkindus) provided the earliest recipe for the production of camphor in his Kitab Kimiya' al-'Itr (Book of the Chemistry of Perfume).[84]Deodorants, under-arm and roll-on: In the 9th century, Ziryab invented under-arm deodorants in Al-Andalus.[23] In circa 1000, another under-arm deodorant was described in Al-Andalus by Abulcasis,[79] who also invented perfumed stocks, rolled and pressed in special moulds, similar to modern roll-on deodorants.[85]Extraction of fragrances through steam distillation: Introduced by Abū Alī ibn Sīnā (Avicenna) in the 11th century.Ghaliya: The preparation of a perfume called ghaliya, which contained musk, amber and other ingredients, and the use of various drugs and apparatus], was produced by al-Kindi.Musk and floral perfumes: Produced in the 11th-12th centuries in the Arabian Peninsula.[81]Jasmine and citrus perfumes: Muslims introduced new raw ingredients in perfumery, which were produced from different spices, herbals, and other fragrance materials, which are still used in modern perfumery. These included jasmine from South and Southeast Asia, and citrus fruits from East Asia.Rose water: See Chemical substances above.[edit] InstitutionsA number of important economic, educational, legal and scientific institutions previously unknown in the ancient world have their origins in the medieval Islamic world. Academic degree-granting university:[86] If the definition of a university is assumed to mean an institution of higher education and research which issues academic degrees at all levels (bachelor, master and doctorate) like in the modern sense of the word, then the medieval Madrasahs known as Jami'ah("university" in Arabic) founded in the 9th century would be the first examples of such an institution.[87][88] The University of Al Karaouine in Fez, Morocco is thus recognized by the Guinness Book of World Records as the oldest degree-granting university in the world with its founding in 859 by Fatima al-Fihri.[89] Also in the 9th century, Bimaristan medical schools were founded in the medieval Islamic world, where medical degrees and diplomas were issued to students of Islamic medicine who were qualified to be a practicing Doctor of Medicine.[88][90] Al-Azhar University, founded in Cairo, Egypt in 975, was a Jami'ah university which offered a variety of post-graduate degrees (Ijazah),[88] and had individual faculties[91] for a theological seminary, Islamic law and jurisprudence, Arabic grammar, Islamic astronomy, early Islamic philosophy, and logic in Islamic philosophy.[88] The modern academic robe worn by graduates was also adapted from the robe worn by the Alim (alumni).[92]Agency and Aval: The first agencies were the Hawala, mentioned in texts of Islamic jurisprudence as early as the 8th century. Hawala itself later influenced the development of the agency in common law and in civil laws such as the Aval in French law and the Avallo in Italian law. The words Aval and Avallo were themselves derived from Hawala. The transfer of debt, which was "not permissible under Roman law but became widely practiced in medieval Europe, especially in commercial transactions", was due to the large extent of the "trade conducted by the Italian cities with the Muslim world in the Middle Ages." The agency was also "an institution unknown to Roman law" as no "individual could conclude a binding contract on behalf of another as his agent." In Roman law, the "contractor himself was considered the party to the contract and it took a second contract between the person who acted on behalf of a principal and the latter in order to transfer the rights and the obligations deriving from the contract to him." On the other hand, Islamic law and the later common law "had no difficulty in accepting agency as one of its institutions in the field of contracts and of obligations in general."[93]Assize of novel disseisin and contract protected by the action of debt: According to Professor John Makdisi, the "royal English contract protected by the action of debt" has origins in "the Islamic Aqd", and "the English assize of novel disseisin" has origins in "the Islamic Istihqaq", in classical Maliki jurisprudence.[94]College: The origins of the college lie in the medieval Islamic world. The madrasah was a medieval Islamic college of law and theology, usually affiliated with a mosque, and was funded by early charitable trusts known as Waqf, the origins of the trust law.[87][95]Jury and jury trial: The closest predecessor to the English jury trial was the Lafif in the Maliki school of classical Islamic law and jurisprudence, which was developed between the 8th and 11th centuries. Like the English jury, the Islamic Lafif was a body of twelve members drawn from the neighborhood and sworn to tell the truth, who were bound to give a unanimous verdict, about matters "which they had personally seen or heard, binding on the judge, to settle the truth concerning facts in a case, between ordinary people, and obtained as of right by the plaintiff." According to John Makdisi, "no other institution in any legal institution studied to date shares all of these characteristics with the English jury."[94]The first observatories to serve as research institutes were built by Muslim astronomers. The most famous was the Maragheh observatory, the current status of which is pictured here. Observatory as a research institute: As opposed to a private observation post as was the case in ancient times,[96] the astronomical observatories in the Islamic world were the first true observatories, in the sense that they functioned as early research institutes, like modern observatories.[86] The Islamic observatory was the first specialized astronomical institution with its own scientific staff,[97] director, astronomical program,[96] large astronomical instruments, and building where astronomical research and observations are carried out. Islamic observatories were also the first to employ enormously large astronomical instruments in order to improve the accuracy of their observations.[97] Famous examples include the observatories at Baghdad and Ray, Iran, the Maragheh observatory, Ulugh Beg's observatory at Samarqand, and the Istanbul observatory of al-Din.Public library and lending library:[86] A number of distinct features of the modern library were introduced in the Islamic world, where libraries not only served as a collection of manuscripts as was the case in ancient libraries, but also as a public library and lending library, a centre for the instruction and spread of sciences and ideas, a place for meetings and discussions, and sometimes as a lodging for scholars or boarding school for pupils. The concept of the library catalogue was also introduced in medieval Islamic libraries, where books were organized into specific genres and categories.[98]Restaurant: See Food and drink above.Trust institution and charitable trust: The Waqfin Islamic law, which developed in the Islamic world from the 7th to 9th centuries, were the first charitable trust.[99] Every waqf was required to have a waqif (founder), mutawillis (trustee), qadi (judge) and beneficiaries.[100] Under both a waqf and a trust, "property is reserved, and its usufruct appropriated, for the benefit of specific individuals, or for a general charitable purpose; the corpus becomes inalienable; estates for life in favor of successive beneficiaries can be created" and "without regard to the law of inheritance or the rights of the heirs; and continuity is secured by the successive appointment of trustees or mutawillis."[101][edit] Medical institutionsSee also: Bimaristan, Islamic medicine, and Islamic psychology Apothecary, Drugstore, and Pharmacy: The first drugstores and pharmacies were opened by Muslim pharmacists in Baghdad in 754,[2] while the first apothecary shops were also founded by Muslim practitioners at the time.[102]Medical school: The Islamic Bimaristans were not only hospitals, but also the first medical schools and universities to issue diplomas. The first of these institutions was opened in Baghdad during the time of Harun al-Rashid. They then appeared in Egypt from 872 and then in Islamic Spain, Persia and the Maghreb thereafter. Physicians and surgeons at Islamic hospital-universities gave lectures to medical students and diplomas were issued to students who completed their education and were qualified to be doctors of medicine.[103]Psychiatric hospital: The first psychiatric hospitals were built in the medieval Islamic world. The first of these were built built in Baghdad in 705, Fes in the early 8th century, and Cairo in 800.[104]Public hospital: The Islamic Bimaristans were the first free public hospitals, and replaced the healing temples and sleep temples found in ancient times.[86] They were hospital in the modern sense, an establishment where the ill were welcomed and cared for by qualified staff. In this way, Muslim physicians were the first to make a distinction between a hospital and other different forms of sleep and healing temples, hospices, assylums, lazarets and leper-houses, all of which in ancient times were more concerned with isolating the sick and the mad from society "rather than to offer them any way to a true cure." The medieval Bimaristan hospitals are thus considered "the first hospitals" in the modern sense of the word.[105]Quarantine: The discovery of the contagious nature of infectious diseases and the use of quarantine to limit the spread of contagious diseases was introduced by Avicenna in The Canon of Medicine (1025).[106]Geriatric medicine: Arabs were the first to write books on Geriatric medicine.[edit] Mechanical technologyAl-Jazari invented the bayonet fitting, camshaft, bolted lock, laminate, paper model, calibrated orifice, sand casting, gate operator, linkage, water level, crank-driven and hydropowered saqiya chain pumps, double-action reciprocating piston suction pump, programmable humanoid robot band, programmable analog computer, flush mechanism, and automated servants. Al-Jazari's candle clock employed a bayonet fitting for the first time in 1206.Drawing of the self-trimming lamp in Ahmad ibn Mūsā ibn Shākir's 9th century Arabic treatise on mechanical devices, the Book of Ingenious Devices.Diagram of a hydropowered water-raising machine from The Book of Knowledge of Ingenious Mechanical Devices by Al-Jazari in 1206.The double-action reciprocating suction piston pump with a valve and crankshaft-connecting rod mechanism, from a manuscript of Al-Jazari, considered to be a "father of modern day engineering".The programmable humanoid robot band of Al-Jazari, considered to be a "father of robotics".The programmable humanoid robot band designed by Al-Jazari in 1206.The hand washing automaton with a flush mechanism designed by Al-Jazari in 1206.Artificial thunder, lightning and weather simulation: Abbas Ibn Firnas invented an artificial weather simulation room, in which spectators saw stars and clouds, and were astonished by artificial thunder and lightning, which were produced by mechanisms hidden in his basement laboratory.[107][108]Bayonet fitting: Al-Jazari's candle clock in 1206 employed, for the first time, a bayonet fitting, a fastener mechanism still used in modern times.[109]Camshaft: The first known use of cams on a camshaft were invented in Iraq by Al-Jazari in 1206.[110] His camshaft was attached to a water wheel and was used to operate levers moving robotic musicians in his castle clock (see Analog computers below).[111]Bolted lock, and mechanical controls: According to Donald Routledge Hill, Al-Jazari first described several early mechanical controls, including "a large metal door...and a lock with four bolts."[70]Complex segmental and epicyclic gearing: Segmental gears ("a piece for receiving or communicating reciprocating motion from or to a cogwheel, consisting of a sector of a circular gear, or ring, having cogs on the periphery, or face."[112]) and epicyclic gears were both first invented by the 11th century Arab engineer Ibn Khalaf al-Muradi from Islamic Spain. He employed both these types of gears in the gear trains of his mechanical clocks. Simple gears have been known before him, but this was the the first known case of complex gears used to transmit high torque.[17] Segmental gears were also later employed by Al-Jazari in 1206. Professor Lynn Townsend White, Jr. wrote: "Segmental gears first clearly appear in Al-Jazari, in the West they emerge in Giovanni de Dondi's astronomical clock finished in 1364, and only with the great Sienese engineer Francesco di Giorgio (1501) did they enter the general vocabulary of European machine design."[113]Design and construction methods: According to Donald Routledge Hill, "We see for the first time in Al-Jazari's work several concepts important for both design and construction: the lamination of timber to minimize warping, the static balancing of wheels, the use of wooden templates (a kind of pattern), the use of paper models to establish designs, the calibration of orifices, the grinding of the seats and plugs of valves together with emery powder to obtain a watertight fit, and the casting of metals in closed mold boxes with sand."[70]Escapement mechanism in rotating wheel: Al-Jazari invented a method for controlling the speed of rotation of a wheel using an escapement mechanism in 1206.[114]Fountain pen: The earliest historical record of a reservoir fountain pen dates back to the 10th century. In 953, Al-Muizz Lideenillah, the caliph of Egypt, demanded a pen which would not stain his hands or clothes, and was provided with a pen which held ink in a reservoir and delivered it to the nib via gravity and capillary action. As recorded by Qadi al-Nu'man al-Tamimi (d. 974) in his Kitdb al-Majalis WA 'l-musayardt, al-Mu'izz instructed and commissioned the construction of a fountain reservoir pen.[115][116]Gate operator: The first automatic doors were created by Hero of Alexandria and Chinese engineers under Emperor Yang of Sui prior to Islam. This was followed by the first hydraulics-powered automatic gate operators, invented by Al-Jazari in 1206.[117] Al-Jazari also created automatic doors as part of one of his elaborate water clocks.[70]Intermittent working: The concept of minimizing intermittent working is first implied in one of al-Jazari's saqiya chain pumps, which was for the purpose of maximising the efficiency of the saqiya chain pump.[118]Metal block printing and printed amulet: Printing was known as tarsh in Arabic. After woodblock printing appeared in the Islamic world, which may have been adopted from China, a unique type of block printing was invented in Islamic Egypt during the 9th-10th centuries: print blocks made from metals such as tin, lead and cast iron, as well as stone, glass and clay. The first printed amulets were invented in the Islamic world, and were printed with Arabic calligraphy using metal block printing. This technique, however, appears to have had very little influence outside of the Muslim world, since metal and other non-wooden forms of block printing were unknown in China or Korea, which later developed metal movable type printing instead. Block printing later went out of use in Islamic Central Asia after movable type printing was introduced from China at least 100 years ago.[119]Metronome: According to Lynn Townsend White, Jr., the Andalusian polymath Abbas Ibn Firnas was the inventor of an early metronome in the 9th century.[30]On/off switch: The on/off switch, an important feedback control principle, was invented by Muslim engineers between the 9th and 12th centuries, and it was employed in a variety of automata and water clocks. The mechanism later had an influence on the development of the electric on/off switch which appeared in the 1950s.[120]In the 9th century, the Banū Mūsā brothers invented a number of automata (automatic machines) and mechanical devices, and they described a hundred such devices in their Book of Ingenious Devices. Some of their original inventions include:Automatic control[17]Feedback controller[121]Differential pressure[122]Fail-safe system[70]Float chamber[17]Hurricane lamp[70]Gas mask[70]Grab and Clamshell grab[70]Self-feeding lamp and self-trimming lamp: Invented by the eldest brother Ahmad ibn Mūsā ibn Shākir.[70]Trick drinking vessels[70]Valve, plug valve,[70][121] and float valve.[121]In 1206, Al-Jazari also described over fifty mechanical devices in six different categories in The Book of Knowledge of Ingenious Mechanical Devices, most of which he invented himself, along with construction drawings. Along with his other mechanical inventions described above, some of the other mechanical devices he first described include: phlebotomy measures, linkage, water level, and devices able to elevate water from shallow wells or flowing rivers.[50][51][123][124][edit] AutomataMark E. Rosheim summarizes the advances in robotics made by Arab engineers as follows:"Unlike the Greek designs, these Arab examples reveal an interest, not only in dramatic illusion, but in manipulating the environment for human comfort. Thus, the greatest contribution the Arabs made, besides preserving, disseminating and building on the work of the Greeks, was the concept of practical application. This was the key element that was missing in Greek robotic science."[125] "The Arabs, on the other hand, displayed an interest in creating human-like machines for practical purposes but lacked, like other preindustrial societies, any real impetus to pursue their robotic science."[126]Mechanical singing bird automata: Caliph al-Mamun had a silver and golden tree in his palace in Baghdad in 827, which had the features of an automatic machine. There were metal birds that sang automatically on the swinging branches of this tree built by Muslim engineers at the time.[127][128] The Abbasid Caliph al-Muktadir also had a golden tree in his palace in Baghdad in 915, with birds on it flapping their wings and singing.[127][129]Programmable automatic flute player: The Banū Mūsā invented an automatic flute player which appears to have been the first programmable machine, and which they described in their Book of Ingenious Devices.[130]Programmable analog computer: See Analog computers below.Programmable humanoid robot band: Al-Jazari (1136-1206) created the first recorded designs of a programmable humanoid robot in 1206, as opposed to the non-programmable automata in ancient times. Al-Jazari's robot was originally a boat with four automatic musicians that floated on a lake to entertain guests at royal drinking parties. His mechanism had a programmable drum machine with pegs (cams) that bump into little levers that operate the percussion. The drummer could be made to play different rhythms and different drum patterns if the pegs were moved around.[131] According to Charles B. Fowler, the automata were a "robot band" which performed "more than fifty facial and body actions during each musical selection."[132]Hand washing automaton with flush mechanism: Al-Jazari invented a hand washing automaton first employing the flush mechanism now used in modern flush toilets. It features a female humanoid automaton standing by a basin filled with water. When the user pulls the lever, the water drains and the female automaton refills the basin.[133]Peacock fountain with automated humanoid servants: Al-Jazari's "peacock fountain" was a sophisticated hand washing device featuring humanoid automata as servants which offer soap and towels. Mark E. Rosheim describes it as follows: "Pulling a plug on the peacock's tail releases water out of the beak; as the dirty water from the basin fills the hollow base a float rises and actuates a linkage which makes a servant figure appear from behind a door under the peacock and offer soap. When more water is used, a second float at a higher level trips and causes the appearance of a second servant figure - with a towel!"[125][edit] PumpsCrankshaft-driven and hydropowered saqiya chain pumps: The first known use of a crankshaft in a chain pump was in one of Al-Jazari's saqiya machines described in 1206.[118] Al-Jazari also constructed a water-raising saqiya chain pump which was run by hydropower rather than manual labour, though the Chinese were also using hydropower for other chain pumps prior to him. Saqiya machines like the ones he described have been supplying water in Damascus since the 13th century up until modern times,[134] and were in everyday use throughout the medieval Islamic world.[118]Crankshaft-driven screw and screwpump: In ancient times, the screw and screwpump were driven by a treadwheel, but from the 12th and 13th centuries, Muslim engineers operated them using the crankshaft.[135]Double-action piston suction pump with reciprocating motion: In 1206, al-Jazari demonstrates the first suction pipes and suction piston pump, the first use of double-action, and one of the earliest valve operations, when he invented a twin-cylinder double-action reciprocating suction piston pump, which seems to have had a direct significance in the development of modern engineering. This pump is driven by a water wheel, which drives, through a system of gears, an oscillating slot-rod to which the rods of two pistons are attached. The pistons work in horizontally opposed cylinders, each provided with valve-operated suction and delivery pipes. The delivery pipes are joined above the centre of the machine to form a single outlet into the irrigation system. This pump is remarkable for being the earliest known use of a true suction pipe in a pump.[136]Flywheel-driven chain pump and noria: A flywheel is used to smooth out the delivery of power from a driving device to a driven machine. The mechanical flywheel was first invented by Ibn Bassal (fl. 1038-1075) of Islamic Spain, who pioneered the use of the flywheel in the chain pump (saqiya) and noria.[137]Weight-driven pump: Most ancient and medieval pumps were either driven by manual labour or hydraulics. The first weight-driven pump was described as part of a perpetual motion water-raising machine in a medieval Arabic manuscript written some time after Al-Jazari. It featured a mercury-powered clockwork escapement mechanism and had two out gear-wheels driven by lead weights which mesh with a large central gear-wheel.[138][edit] Medical productsSee also: Islamic medicine [edit] Drugs and medicationsMuslim physicians pioneered a number of drugs and medications for use in medicine, including:Avicenna, considered the "father of modern medicine", pioneered clinical pharmacology, and described inhalational anesthetics and various drugs and medications, in The Canon of Medicine (1025). Alcohol as an antiseptic: The application of pure alcohol to wounds as an antiseptic agent, and the use of alcohol as a solvent and antiseptic, was introduced by Muslim physicians and surgeons in the 10th century.[9]Cancer therapy, pharmacotherapy, and Hindiba: Avicenna's The Canon of Medicine (1025) attempted the earliest known treatments for cancer. One method he discovered was the "Hindiba", a herbal compound drug which Ibn al-Baitar later identified as having "anticancer" properties and which could also treat other tumors and neoplastic disorders. Avicenna wrote a separate supplement treatise dedicated to the pharmacotherapy of Hindiba, giving details on the drug's properties and uses, and he then gives instructions on its preparation as medication.[139] After recognizing its usefulness in treating neoplastic disorders, Hindiba was patented in 1997 by Nil Sari, Hanzade Dogan and John K. Snyder.[140]Chemotherapeutic drugs: Pioneered by Muhammad ibn Zakarīya Rāzi (Rhazes), who introduced the use of chemical substances such as vitriol, copper, mercuric and arsenic salts, sal ammoniac, gold scoria, chalk, clay, coral, pearl, tar, bitumen and alcohol for medical purposes.[141]Clinical pharmacology, clinical trial, randomized controlled trial, and efficacy test: The origins of clinical pharmacology date back to Avicenna's The Canon of Medicine in 1025.[142] His emphasis on tested medicines laid the foundations for an experimental approach to pharmacology.[143] The Canon laid out the rules and principles for testing the effectiveness of new drugs and medications, which still form the basis of clinical pharmacology[144] and modern clinical trials,[145] randomized controlled trials[146][147] and efficacy tests.[148][149]Cough medicine and syrup: The use of syrups for treating coughs originates from medieval Arabic physicians.[14][150]Drugs, foods, herbs, plants and chemical substances: In antiquity, Dioscorides listed about 500 plants in the 1st century. Muslim botanists, chemists and pharmacists dicovered many more during the Middle Ages. For example, Al-Dinawari described more than 637 plant drugs in the 9th century,[151] and Ibn al-Baitar described at least 1,400 different plants, foods and drugs, 300 of which were his own original discoveries, in the 13th century.[152] In total, at least 2,000 medicinal substances were discovered by Muslim botanists, chemists and pharmacists.[2]Epilepsy and seizure medications: Abulcasis, in his Al-Tasrif (c. 1000), invented medications called Ghawali and Lafayfe for the treatment of epilepsy and seizure.[79]Medicinal-grade alcohol: Produced through distillation. These distillation devices for use in chemistry and medicine were manufactured on a large scale in the 10th century.Parasitology: Parasites were first discovered by Ibn Zuhr (Avenzoar), when he discovered the cause of scabies.[153] He recommended specific substances to destroy microbes, and the application of sulfur topically specifically to kill the scabies mite.Pharmacopoeia: The first pharmacopoeia books were written by Muslim physicians.[154] These included Avicenna's The Canon of Medicine and other pharmacopoeia books by Abu-Rayhan Biruni in the early 11th century,[155] Ibn Zuhr (Avenzoar) in the 12th century (and printed in 1491),[156] and Ibn al-Baitar in the 14th century.[9]Phytotherapy, Taxus baccata, and calcium channel blocker: Avicenna's The Canon of Medicine introduced the medicinal use of Taxus baccata L. He named this herbal drug "Zarnab" and used it as a cardiac remedy. This was the first known use of a calcium channel blocker drug, which were not used in the Western world until the 1960s.[157]Sexual dysfunction and erectile dysfunction drugs: Muslim physicians identified the issue of sexual and erectile dysfunction, and they were the first to prescribe medication for the treatment of the problem. They developed several methods of therapy for this issue, including the single drug method where a drug is prescribed, and a "combination method of either a drug or food." These drugs were also occasionally used for recreational drug use to improve male sexuality in general by those who did not suffer from sexual dysfunctions. Most of these drugs were oral medication, though a few patients were also treated through topical and transurethral means. Sexual dysfunctions were being treated with tested drugs in the Islamic world since the 9th century until the 16th century by a number of Muslim physicians and pharmacists, including al-Razi, Thabit bin Qurra, Ibn Al-Jazzar, Avicenna (The Canon of Medicine), Averroes, Ibn al-Baitar, and Ibn al-Nafis (The Comprehensive Book on Medicine).[158]Topical cream: For the relief and treatment of common colds, Abulcasis invented Muthallaathat, which was prepared from camphor, musk and honey, similar to the modern Vicks Vapour Rub.[79][edit] Surgical instrumentsA wide variety of surgical instruments and techniques were invented in the Muslim world, as well as the refinement of earlier instruments and techniques. In particular, over 200 surgical instruments were listed by Abu al-Qasim al-Zahrawi (Abulcasis) in the Al-Tasrif (1000), many of which were never used before by any previous surgeons. Hamidan, for example, listed at least twenty six innovative surgical instruments that Abulcasis introduced. Adhesive bandage and plaster: Introduced by Abulcasis.[159][160]Bone saw: Invented by Abulcasis.[10]Cancer surgery: Another method for treating cancer first described by Avicenna's The Canon of Medicine was a surgical treatment. He stated that the excision should be radical and that all diseased tissue should be removed, which included the use of amputation or the removal of veins running in the direction of the tumor. He also recommended the use of cauterization for the area being treated if necessary.[159]Cataract extraction, hypodermic needle, injection syringe, and suction: In circa 1000, the Muslim ophthalmologist Ammar ibn Ali of Mosul was the first to successfully extract cataracts. He invented a hollow metallic syringe hypodermic needle, which he applied through the sclerotic and successfully extracted the cataracts through suction.[161]Catgut, use of: The use of catgut for internal stitching was introduced by Abulcasis.Cotton dressing and bandage: The earliest known use of cotton (derived from the Arabic word qutn) as a dressing for controlling hemorrhage, was described by Abulcasis.[159]Curette, retractor, sound, surgical spoon, surgical hook, and surgical rod: Invented by Abulcasis in his Al-Tasrif(1000).[162]Fetus extraction: Abulcasis, in his Al-Tasrif(1000), first described the surgical procedure of extractiing a dead fetus using forceps.[163]General anaesthesia, General anaesthetic, oral anesthesia, inhalational anaesthetic, and narcotic-soaked sponge: Surgeries under inhalant anesthesia with the use of narcotic-soaked sponges which were placed over the face, were introduced by the Muslim anesthesiologists, Abu al-Qasim (Abulcasis) and Ibn Zuhr, in Islamic Spain. Sigrid Hunke wrote: "The science of medicine has gained a great and extremely important discovery and that is the use of general anaesthetics for surgical operations, and how unique, efficient, and merciful for those who tried it the Muslim anaesthetic was. It was quite different from the drinks the Indians, Romans and Greeks were forcing their patients to have for relief of pain. There had been some allegations to credit this discovery to an Italian or to an Alexandrian, but the truth is and history proves that, the art of using the anaesthetic sponge is a pure Muslim technique, which was not known before. The sponge used to be dipped and left in a mixture prepared from cannabis, opium, hyoscyamus and a plant called Zoan."[164]Illustrated surgical atlas: Şerafeddin Sabuncuoğlu's Cerrahiyyetu'l-Haniyye (Imperial Surgery), produced in the 15th century, was the first surgical wiktionary:atlas|atlas. Surgical operations were illustrated for the first time in the Cerrahiyyetu'l-Haniyye.[165]Ligature: Introduced by Abulcasis in the Al-Tasrif, for the blood control of arteries in lieu of cauterization.[166]Surgical suture: Abulcasis in his Al-Tasrif.[167]Tracheotomy, correct description of: While tracheostomy may have possibly been portrayed on ancient Egyptian tablets, the first clear and correct description of the tracheotomy operation for suffocating patients was described by Ibn Zuhr (Avenzoar) in the 12th century.[167][168][edit] Navigational technologySee also: Geography in medieval Islam, Astronomy in medieval Islam, and Physics in medieval Islam The 32-point compass rose was invented by Arab navigators. Shown here is the one by Jorge de Aguiar (1492).[edit] InstrumentsBaculus: The baculus, used for nautical astronomy, originates from Islamic Spain and was later used by Portuguese navigators for long-distance travel.[169]Cartographic grids: Invented in 10th-century Baghdad.[170]Compass dial: In the early 14th century, Ibn al-Shatir invented the compass dial, a timekeeping device incorporating both a universal sundial and a magnetic compass. He invented it for the purpose of finding the times of Salah prayers.[171]Compass rose: The Arabs invented the 32-point compass rose during the Middle Ages.[172]Navigational astrolabe: Invented in the Islamic world, it employed the use of a polar projection system.[173]Orthographical astrolabe: Invented by Abū Rayhān al-Bīrūnī in the early 11th century.[174]Terrestrial globe: See Globes below.[edit] TransportKamal: Arab navigators invented a rudimentary sextant known as a kamal, used for celestial navigation and for measuring the altitudes and latitudes of the stars, in the late 9th century.[175] They employed in the Indian Ocean from the 10th century,[176] They employed it in the Indian Ocean from the 10th century,[176] and it was adopted by Indian navigators soon after,[177] followed by Chinese navigators some time before the 16th century.[178] The invention of the kamal allowed for the earliest known latitude sailing,[176] and was thus the earliest step towards the use of quantitative methods in navigation.[178]Rudder with tackles, permanent sternpost-mounted: The Arabs used a sternpost-mounted rudder which differed technically from both its European and Chinese counterparts. On their ships "the rudder is controlled by two lines, each attached to a crosspiece mounted on the rudder head perpendicular to the plane of the rudder blade."[179] The earliest evidence comes from the Ahsan al-Taqasim fi Marifat al-Aqalim ('The Best Divisions for the Classification of Regions') written by al-Muqaddasi in 985.[180] According to Lawrence V. Mott, the "idea of attaching the rudder to the sternpost in a relatively permanent fashion, therefore, must have been an Arab invention independent of the Chinese."[179]Minaret of the Great Mosque at Córdoba, where Abbas Ibn Firnas flew from in the 9th century. [edit] AviationParachute: In 9th century Islamic Spain, Abbas Ibn Firnas (Armen Firnas) invented a primitive version of the parachute.[181][182][183][184] John H. Lienhard described it in The Engines of Our Ingenuity as follows: "In 852, a new Caliph and a bizarre experiment: A daredevil named Armen Firman decided to fly off a tower in Cordova. He glided back to earth, using a huge winglike cloak to break his fall."[185][edit] Scientific instrumentsSee also: Islamic astronomy, Islamic physics, and Alchemy and chemistry in Islam Muslim astronomers developed a number of astronomical instruments, including several variations of the astrolabe, originally invented by Hipparchus in the 2nd century BCE, but with considerable improvements made to the device in the Muslim world. These instruments were used by Muslims for a variety of purposes. In the 10th century, Al-Sufi first described over 1,000 different uses of an astrolabe, related to astronomy, astrology, horoscopes, navigation, surveying, timekeeping, Qibla (direction to Mecca), Salah prayers, etc.[186][edit] Analog computersThe universal latitude-independent astrolabe was invented by Abū Ishāq Ibrāhīm al-Zarqālī (Arzachel) in Islamic Spain circa1015. The one shown here is from Persia in the 18th century. The spherical astrolabe was invented by Muslim astronomers. This is the earliest surviving example from the 14th century.Equatorium: Invented by Abū Ishāq Ibrāhīm al-Zarqālī (Arzachel) in Islamic Spain circa 1015,[17] it was a mechanical analog computer device for finding the longitudes and positions of the moon, sun, and planet]s, without calculation using a geometrical model to represent the celestial body's mean and anomalistic position.Saphaea: The first universal latitude-independent astrolabe, invented by Abū Ishāq Ibrāhīm al-Zarqālī (Arzachel) in 11th century Islamic Spain. Unlike its predecessors, it did not depend on the latitude of the observer, and could be used anywhere on the Earth.[187]Zuraqi: A heliocentric astrolabe where the Earth is in motion rather than the sky, by al-Sijzi in the 11th century.[188]Fixed-wired knowledge processing machine: Abū Rayhān al-Bīrūnī's hodometer[189] was an early example of a fixed-wired knowledge processing machine in the early 11th century.[190]Mechanical lunisolar calendar computer: Featured a gear train and gear-wheels, and was invented by Abū Rayhān al-Bīrūnī.[191]Mechanical geared astrolabe: Invented by Ibn Samh (c. 1020).[192]Linear astrolabe ("staff of al-Tusi"): Invented by Sharaf al-Dīn al-Tūsī in the 12th century.[193]Programmable analog computer: The castle clock, an astronomical clock invented by Al-Jazari in 1206, is considered to be the earliest programmable analog computer.[111] It displayed the zodiac, the solar and lunar orbits, a crescent moon-shaped pointer travelling across a gateway causing automatic doors to open every hour,[70][194] and five robotic musicians who play music when moved by levers operated by a camshaft attached to a water wheel. The length of day and night could be re-programmed every day in order to account for the changing lengths of day and night throughout the year.[111]Mechanical geared astrolabe with calendar computer: Invented by Abi Bakr of Isfahan in 1235.[195]Plate of Conjunctions: A computing instrument used to determine the time of day at which planetary conjunctions will occur,[196] and for performing linear interpolation,[197] invented by al-Kashi in the 15th century.Planetary computer: The Plate of Zones, a mechanical planetary computer which could graphically solve a number of planetary problems, was invented by al-Kashi in the 15th century. It could predict the true positions in longitude of the sun and moon,[197] and the planets in terms of elliptical orbits;[198] the latitudes of the Sun, Moon, and planets; and the ecliptic of the Sun. The instrument also incorporated an alidade and ruler.[199][edit] Laboratory apparatusGeber invented the alembic, the first still with a retort, and the first distillation device to fully purify chemical substances. Alembic, still, and retort: Jabir ibn Hayyan (Geber) invented the alembic in the 8th century. This was the first still[3] with a retort,[200] and the first distillation device to fully purify chemical substances.Conical measure: Abū Rayhān al-Bīrūnī in the 11th century.[201][202]Hydrostatic balance and steelyard: Al-Khazini in 1121.[203]Laboratory flask and pycnometer: Abū Rayhān al-Bīrūnī.[203]Refrigerated coil and refrigerated tubing: In the 11th century, Avicenna invented the refrigerated coil, which condenses aromatic vapours.[204][205] This was a breakthrough in distillation technology and he made use of it in his steam distillation process, which requires refrigerated tubing, to produce essential oils.[11]Thermometer and air thermometer: Abū Alī ibn Sīnā (Avicenna) in the 11th century.[206]Tools for drug preparation: Muhammad ibn Zakarīya Rāzi (Rhazes) first described the following tools for the preparation of drugs (li-tadbir al-aqaqir): cucurbit and still with evacuation tube (qar aq anbiq dhu-khatm), receiving matras (qabila), blind still (without evacuation tube) (al-anbiq al-ama), aludel (al-uthal), goblets (qadah), flasks (qarura or quwarir), rosewater flasks (ma wariyya), cauldron (marjal aw tanjir), earthenware pots varnished on the inside with their lids (qudur aq tanjir), water bath or sand bath (qadr), oven (al-tannur in Arabic, athanor in Latin), small cylindirical oven for heating aludel(mustawqid), funnels, sieves, and filters.[6]Tools for melting substances: Al-Razi (Rhazes), in his Secretum secretorum (Latinized title), described the following original tools for melting chemical substances (li-tadhwib): crucible (bawtaqa)[6] and kilns with superimposed crucibles known as but bar but (crucible on crucible) in Arabic and botus barbatusin Latin.[207][edit] Mural instrumentsThe first sextant was built in Ray, Iran by Abu-Mahmud al-Khujandi in 994. The earliest surviving sextant is Ulugh Beg's mural "Fakhri Sextant" constructed in Samarkand, Uzbekistan, during the 15th century, pictured above. Quadrant and mural instrument: Invented by Al-Khwarizmi in 9th century Baghdad, Iraq.[208]Almucantar quadrant: Invented in the medieval Islamic world. It employed the use of trigonometry. The term "almucantar" is itself derived from Arabic.[209]Horary quadrant: For specific latitude]s, by al-Khwarizmi in 9th century Baghdad.[208]Sine quadrant: For astronomical calculations, by al-Khwarizmi in 9th century Baghdad.[208]Quadrans Vetus: Meaning "Old Quadrant", this was a universal horary quadrant which could be used for any latitude and at any time of the year to determine the time, as well as the times of Salah, invented by al-Khwarizmi in 9th century Baghdad. This was the second most widely used astronomical instrument during the Middle Ages after the astrolabe. One of its main purposes in the Islamic world was to determine the times of Salah prayers.[210]Quadrans Novus: An astrolabic quadrant invented in Egypt in the 11th century or 12th century, and later known in Europe as the "Quadrans Novus" (New Quadrant).[211]Sextant: The first sextant was constructed in Ray, Iran, by Abu-Mahmud al-Khujandi in 994. It was a very large sextant that achieved a high level of accuracy for astronomical measurements, which he described his in his treatise, On the obliquity of the ecliptic and the latitudes of the cities.[212] In the 15th century, Ulugh Beg constructed the mural "Fakhri Sextant", which had a radius of approximately 36 meters. Constructed in Samarkand, Uzbekistan, the arc was finely constructed with a staircase on either side to provide access for the assistants who performed the measurements.[edit] Optical instrumentsIn ancient times, Euclid and Ptolemy believed that the eyes emitted rays which enabled us to see. The first person to realise that rays of light enters the eye, rather than leaving it, was the 10th century Muslim mathematician, astronomer and physicist Ibn al-Haytham (Alhazen), who is regarded as the "father of optics".[213] He is also credited with being the first man to shift physics from a philosophical activity to an experimental one, with his development of the scientific method. Observation tube: The "observation tube" (without lens) was invented by al-Battani (Albatenius) (853-929) and first described by al-Biruni (973-1048). These observation tubes were later adopted in Europe, where they influenced the development of the telescope.[214]Modern optics: Ibn al-Haytham (Alhazen), with his Book of Optics (1021), refuted the emission theory of vision, and correctly explained and proved the modern intromission theory of vision, through extensive experimentation. He thus initiated a revolution in optics[215] and visual perception,[216] for which he is regarded as the "father of modern optics".[217]Camera obscura: Ibn al-Haytham worked out that the smaller the hole, the better the picture, and set up the first camera obscura,[10] a precursor to the modern camera.Pinhole camera: Ibn al-Haytham first described pinhole camera after noticing the way light came through a hole in window shutters.[10]Magnifying glass: The earliest evidence of "a magnifying device, a convex lens forming a magnified image", dates back the Book of Optics published by Ibn al-Haytham in 1021. The Latin translation of his work was instrumental to the later inventions of eyeglasses,[218] the telescope,[219] and the microscope.[220][edit] Other instrumentsAn alidade (al-idhâdah "ruler" in Arabic). Alidade: Invented in the Islamic world. The term "alidade" is itself derived from Arabic word al-idhâdah"ruler".Astrolabic clock: Ibn al-Shatir in the early 14th century.[221]Astrometric devices: Produced in Islamic Spain around 1015.Astronomical compass: The first astronomical uses of the magnetic compass is found in a treatise on astronomical instruments written by the Yemeni sultan al-Ashraf in 1282. This was the first reference to the compass in astronomical literature.[222]Compendium instrument: A multi-purpose astronomical instrument, first constructed by the Muslim astronomer Ibn al-Shatir in the 13th century. His compendium featured an alidade and polar sundial among other things. Al-Wafa'i developed another compendium in the 15th century which he called the "equatorial circle", which also featured a horizontal sundial. These compendia later became popular in Renaissance Europe.[223]Shadow square: An instrument used to determine the linear height of an object, in conjunction with the alidade for angular observations, invented by Muhammad ibn Mūsā al-Khwārizmī in 9th-century Baghdad.[224][edit] Timekeeping devicesA sundial in Seville, Andalusia. The first universal and polar-axis sundials were invented by Muslim engineers. The elephant clock from Al-Jazari's manuscript in 1206. This was the earliest clock to employ a flow regulator, a closed-loop system, and an automaton like a cuckoo clock].[edit] Astronomical clocksMuslim astronomers and engineers constructed a variety of highly accurate astronomical clocks for use in their observatories. [9] Timekeeping astrolabe: In the 10th century, al-Sufi described over 1,000 different uses of an astrolabe, including timekeeping, particularly for the times of Salah prayers and Ramadan.[186]Geared mechanical lunisolar calendar computer: See Analog computers above.Geared mechanical astrolabe: Featured a calendar computer and gear-wheels, and was invented by Abi Bakr of Isfahan in 1235.[195]Monumental water-powered astronomical clocks: Al-Jazari invented monumental water powered astronomical clocks which displayed moving models of the sun, moon, and stars. His largest astronomical clock displayed the zodiac and the solar and lunar orbits. Another innovative feature of the clock was a pointer which travelled across the top of a gateway and caused automatic doors to open every hour.[70]Programmable castle clock: See Analog computers above.Quadrans Vetus: See Mural instruments above.[edit] Clocks with gears and escapementsGeared clock: The first geared clock was invented by the 11th-century Arab engineer Ibn Khalaf al-Muradi in Islamic Iberia; it was a water clock that employed both segmental and epicyclic gearing.[17] Other monumental water clocks constructed by medieval Muslim engineers also employed complex gear trains and arrays of automata.[225] The first European clock to employ these complex gears was the astronomical clock created by Giovanni de Dondi in c. 1365.[17]Weight-driven mercury clock: A mercury clock, employing a mercury escapement mechanism[225] and a clock face similar to an astrolabe dial, was described in a Spanish language work for Alfonso X in 1277, compiled from earlier Arabic sources that likely date back to the 11th century.[17] The Jewish author of the relevant section, Rabbi Isaac, constructed the mercury clock using principles described by a philosopher named "Iran", identified with Heron of Alexandria (fl. 1st century AD), on how heavy objects may be lifted.[226] Knowledge of the mercury clock was later transmitted to other parts of Europe through translations.[9][17]Weight-driven water clock: Arab engineers invented weight-driven water clocks, where heavy floats were used as weights and a constant-head system was used as an escapement mechanism,[17] which was present in in the hydraulic controls they used to make heavy floats descend at a slow and steady rate.[225]Weight-driven water-powered scribe clock: In 1206, Al-Jazari invented some of the earliest weight-driven water clocks, including the water-powered scribe clock. This water-powered portable clock was a meter high and half a meter wide. The scribe with his pen was synonymous to the hour hand of a modern clock. This is an example of an ingenious water system by Al-Jazari.[51][227] Al-Jazari's famous water-powered scribe clock was reconstructed successfully at the Science Museum (London) in 1976.[edit] DialsUniversal sundial: A universal sundial for all latitudes, used for timekeeping and for the determination of the times of Salah, was produced in 9th-century Baghdad.[228]Navicula de Venetiis: A universal horary dial used for accurate timekeeping by the sun and stars, and could be observed from any latitude, invented in 9th century Baghdad.[229] This was later considered the most sophisticated timekeeping instrument of the Renaissance.[170]Polar-axis sundial: The ancient sundials were nodus-based with straight hour-lines, they indicated unequal hours-also called temporary hours-that varied with the seasons, since every day was divided into twelve equal segments; thus, hours were shorter in winter and longer in summer. The idea of using hours of equal time length throughout the year was the innovation of Ibn al-Shatir in 1371, based on earlier developments in trigonometry by Muhammad ibn Jābir al-Harrānī al-Battānī (Albategni). Ibn al-Shatir was aware that "using a gnomon that is parallel to the Earth's axis will produce sundials whose hour lines indicate equal hours on any day of the year." His sundial is the oldest polar-axis sundial still in existence. The concept later appeared in Western sundials from at least 1446.[230][231]Compass dial: See Instruments above.[edit] Water clocksGeared water clock: See Clocks with gears and escapements above.Elephant clock: The elephant clock described by al-Jazari in 1206 is notable for several innovations. It was the first clock in which an automaton reacted after certain intervals of time, which in this case was a humanoid robot in the form of a mahout striking a cymbal and a mechanical bird chirping like a cuckoo clock; the first mechanism to employ a flow regulator; and the earliest example of a closed-loop system in a mechanism.[232] The float regulator employed in the clock later had an important influence during the Industrial Revolution of the 18th century, when it was employed in the boiler of a steam engine and in domestic water systems.[17]Programmable castle clock: See Analog computers above.Weight-driven water clock: See Clocks with gears and escapements above.Weight-driven water-powered scribe clock: See Clocks with gears and escapements above.New water clocks discovery in the Book of secrets is shown in the Museum of Islamic Art; Doha, Qatar.

Garrison wrote in the History of Medicine:"The Saracens themselves were the originators not only of algebra, chemistry, and geology, but of many of the so-called improvements or refinements of civilization, such as street lamps, window-panes, firework, string instruments, cultivated fruits, perfumes, spices, etc."[233]Other inventions from the Islamic world include:Airmail system utilizing homing pigeons by the Fatimid Caliph Aziz, and advances in music theory (see Arabic music) and irrigation techniques (see Muslim Agricultural Revolution).[234][235][236]Cryptanalysis and frequency analysis: In cryptology, the first known recorded explanation of cryptanalysis was given by 9th-century Arabian polymath, Al-Kindi (also known as "Alkindus" in Europe), in A Manuscript on Deciphering Cryptographic Messages. This treatise includes the first description of the method of frequency analysis.[237] It has been suggested that close textual study of the Qur'an first brought to light that Arabic has a characteristic letter frequency. Its use spread, and similar systems were widely used in European states by the time of the Renaissance.Experimental psychology: Ibn al-Haytham (Alhazen) is considered to be the founder of experimental psychology,[238] for his experimental approach to the psychology of visual perception and optical illusions.[239]Geomancy: The most widely accepted origin for this practice is in the medieval Arabic world.[240]Fireproof paper, glow-in-the-dark ink, rust-free iron, and waterproof textile: According to Ismail al-Faruqi and Lois Lamya al-Faruqi, "In response to Jafar al-Sadik's wishes, [Jabir ibn Hayyan] invented a kind of paper that resisted fire, and an ink that could be read at night. He invented an additive which, when applied to an iron surface, inhibited rust and when applied to a textile, would make it water repellent."[241]Fustian: The original medieval fustian was a stout but respectable cloth with a cotton weft and a linen warp, derived from El-Fustat, the name of a suburb of Cairo where this cloth was originally manufactured.[242][243]Graph paper, and orthogonal and regular grids: The first known use of graph paper dates back to the medieval Islamic world, where weavers often carefully drew and encoded their patterns onto graph paper prior to weaving.[244] Islamic quadrants used for various astronomical and timekeeping purposes from the 10th century also introduced markings with orthogonal and regular grids that are still identical to modern graph paper.[245][246]Persian carpet and cheque system[10]Scientific method, experimental science, and experimental physics: The scientific method was pioneered by the Muslim scientist and physicist, Ibn al-Haytham (Alhazen), who emphasized the role of experimentation and mathematics in obtaining the results in his Book of Optics (1021).[247] Due to his formulation of a modern quantitative, empirical and experimental approach to physics and science, he is also considered the pioneer of experimental science[248] and experimental physics,[249] and some have described him as the "first scientist" for these reasons.[250][edit] Musical instrumentsSee also: Arabic music, Islamic music, and Andalusian classical music Albogue, alboka, hornpipe, clarinet, and single-reed instrument: The earliest known hornpipes, clarinets and single-reed instruments were the albogue and alboka, both derived from the "al-bûq" (البوق) (literally "the trumpet" or "the horn") used in medieval Arabic music and Islamic music. The instrument was brought into Iberia by the Arab conquest.[251]Guitar, lute, and oud: The modern guitar (qitarin Arabic) is descended from the four-string oud brought by the Moors after the Umayyad conquest of Hispania in the 8th century, and which evolved into the modern lute.[252] The four-string guitar introduced by the Moors had eventually evolved into two types in Spain: the guitarra morisca (Moorish guitar) which had a rounded back, wide fingerboard and several soundholes, and then by 1200, the guitarra latina (Latin guitar) which resembled the modern guitar with one soundhole and a narrower neck.[253]Herdy Gerdy and stringed keyboard instrument: The earliest stringed instrument with a musical keyboard, an ancestor of the piano, was the hurdy gurdy, but its origins are uncertain. According to a theory proposed by Marianne Bröcker, an instrument similar to the hurdy gurdy is first mentioned in an Arabic musical compendium written by Al Zirikli in the 10th century.[254]Long-distance organ: A long-distance hydraulic organ that could be heard from sixty miles away was first described in the medieval Arabic treatise Sirr al-asrar and later translated into Latin by Roger Bacon in the 13th century.[255]Mechanical musical instrument and automatic hydraulic organ: The Banū Mūsā brothers invented "the earliest known mechanical musical instrument", in this case a hydropowered organ which played interchangeable cylinders automatically. According to Charles B. Fowler, this "cylinder with raised pins on the surface remained the basic device to produce and reproduce music mechanically until the second half of the nineteenth century."[256]Programmable automatic flute player: The Banū Mūsā invented an automatic flute player which appears to have been the first programmable machine, and which they described in their Book of Ingenious Devices.[130]Timpani, naker, and naqareh: The modern timpani (kettle drum) evolved from the naker, the direct ancestor of most timpani, were were derived from the Arabic naqareh and brought to 13th century Continental Europe by Saracens and Crusaders.[251][257]Rebec, and rebab: The rebec was in use since the 10th century,[258] and was derived from the rebab which originated in medieval Arabic music and Islamic music.[251][edit] See alsoIslamic contributions to Medieval EuropeIslamic Golden AgeMuslim Agricultural RevolutionScience in medieval IslamTimeline of Islamic science and engineeringTimeline of historic inventions[edit] Notes^ Bernard Lewis, What Went Wrong:"There have been many civilizations in human history, almost all of which were local, in the sense that they were defined by a region and an ethnic group. This applied to all the ancient civilizations of the Middle East-Ancient Egypt, Babylon, Persia; to the great civilizations of Asia-India, China; and to the civilizations of Pre-Columbian America. There are two exceptions: Christendom and Islam.
