Al-Mujadalah (The disputation).
The Quran 4:125 God bless
Allah the Al Mighty says in the Quran: al yawma akmaltu lakoum Deenukum in chapter Al Maida
Yes, Quran says (meaning English translation):"O you believe!...But if you pardon (them) and overlook, and forgive (their faults), then verily Allah is oft-Forgiving, Most Merciful"[Quran, chapter 64, verse 14]" Those who spend (in Allah cause) in prosperity and in adversity, who repress anger, and who pardon people; verily Allah loves the good-doers"[Quran, chapter 3, verse 134]" Have you seen those who claim sanctity for themselves. Nay, but Allah sanctifies whom He wills, and they will not be dealt with injustice..."[Quran, chapter 4, Verse 49]See the related question, below, for more information.
Allah sent Ababils ( birds ) who destroyed army of Abraha .Quran says (Meaning English translation):"Have you not considered, [O Muhammad], how your Lord (Allah) dealt with the companions of the elephant [Abraha and his companions]? (1) Did He not make their plan into misguidance? (2) And He sent against them birds in flocks, (3) Striking them with stones of hard clay, (4) And He made them like eaten straw. (5) "(Quran, chapter 105, verses 1-5)
In christian point of view, God is the father, son and holy spirit (Nauz u Billah). This is totally against the oneness of Allah and His mightiness. In Quran Allah says "(O people) say that He is Allah, the One and Unique. Allah, Who is in need of none and of Whom all are in need. He neither begot (is the father of) any nor was He begotten (a son). and none is comparable to Him" [ Surah Ikhlas, Chapter 112, Verses 1-4]. In Quran Allah is totally denying the christian school of thought, so there is no reason for Muhammad (S.A.A.W) to enter a church. When Allah says Himself that he is not what christians say he is then there is no reason for to believe a lie which Allah himself has told is a lie.
Quran says (meaning English translation): (Quran chapter 3, verses 32-33)"Say, "Obey Allah and the Messenger." But if they turn away - then indeed, Allah does not like the disbelievers. (32) Indeed, Allah chose Adam and Noah and the family of Abraham and the family of 'Imran over the worlds - (33) Descendants, some of them from others." Where it is stated that Allah (God in English and same God worshiped in Christianity and Judaism) chose Adam and Noah and the family of Abraham and Imran. You conclude that Adam is Muslim since all those chosen by Allah are assigned to call for Islam and accordingly should be Muslims.
The two main indispensable sources of principles & laws in Islam are the Holy Quran which contains The Almighty Allah's speech , & Al-Sunnah which contains the details of every day in the life of the prophet Muhammad PBUH, what he said,what he did, what he allowed the Muslims to do, what he commanded them to do,what he prohibited ..etc.About the relation between them, they are very attached to each other. I'll give you some points for the purpose of clarification:1. Allah in the Holy Quran commanded the Muslims to be followers of the prophet Muhammad PBUH. Allah says :" Ye have indeed in the Messenger of Allah a beautiful pattern (of conduct) for any one whose hope is in Allah and the Final Day, and who engages much in the Praise of Allah."( chapter 33, verse 21 ) Al-Ahzab (The Clans, The Coalition, The Combined Forces)Also, Allah says:" .... So take what the Messenger assigns to you, and deny yourselves that which he withholds from you. And fear Allah. for Allah is strict in Punishment. "( chapter 59, verse 7 ). Al-Hashr (Exile, Banishment)Also, Allah says :"By the Star when it goes down,-2. Your Companion is neither astray nor being misled.3. Nor does he say (aught) of (his own) Desire.4. It is no less than inspiration sent down to him:5. He was taught by one Mighty in Power"( chapter 53, verses 1 -5 ). An-Najm (The Star)2. Many of the commands of Allah can't be done without following Al-sunnah. For example Allah commanded the Muslims to pray, but the method of the prayer is illustrated in all of its details by the prophet Muhammad PBUH.3. Also, some verses of the Holy Quran can be explained by other verses of the Holy Quran (maybe in other chapters ), or they can be explained by Al-Sunnah.4. The prophet Muhammad PBUH had clearly commanded the Muslims to be strongly tenacious to both of the Holy Quran & his Sunnah, & he PBUH told that if the Muslims do that they'll never be astray or misled.
It says Allah has chosen Adam, Noah, the family of Abraham, and the family of Amram (as messengers) to the people. Qur'an [3:33]
It is the compulsory gathering praying and preceded by a sermon.Quran says (meaning English translation):{O you who believe! when the call is made for prayer on Friday, then hasten to the remembrance of Allah and leave off trading; that is better for you, if you know. (9) But when the prayer is ended, then disperse abroad in the land and seek of Allah's grace, and remember Allah much, that you may be successful. (10)} (Quran, chapter 62, verses 9-10)
We can use any of Allah names when praying or asking him for what we need.Quran says (English meaning translation):"Say (O Muhammad): Invoke Allah or invoke the Most Gracious (Allah), by whatever name you invoke Him (it is the same), for Him belong the Best Names...."(Quran, chapter 17, verse 110)
Allah says in the Quran,"And do not kill yourselves . Surely, Allah is Most Merciful to you."Qur'an - An-Nisa 4:29Suicide in any form is strictly forbidden by Allah.
Islam religion per quran and Prophet Muhammad (PBUH) teachings set the general rules selecting the ruler and for the relation between the ruler and his people. The ruler is obliged to consult his people in all people affairs. However, this should be subject to Islam basic principles and teachings. For example, never people consultation is done for allowing to drink alcohols, to perform fornication, allowing nudity, ... etc. Even prophet Muhammad consulted his people and changed his opinion in many situations to comply with the majority (but this never be in religious ruling and/or ritual worship)Quran, the holy book of Islam, says (meaning English translation):" pass over (call to prophet Mohamed) their faults, ask Allah (God) to forgive them, and consult them in affairs..."[Quran, chapter 3, verse 159] and:" ... those who answer the call of their Lord (means believe in his oneness) and perform prayers and who conduct their affairs by mutual consultation..."[Quran, chapter 42, verse 38] Also Allah (God in English) Says,"And whosoever does not judge by what Allah has revealed, such are the disbelievers."[Quran, chapter 5, verse 45]"And so judge among them by what Allah has revealed.)"[Quran, chapter 5, verse 44]And whosoever does not judge by what Allah has revealed, such are the rebellious.[Quran, chapter 5, verse 46]
