Quran (Koran)

The second verse of the chapter of Quraysh (# 106):

In the name of Allah, Most Gracious, Most Merciful.

1. For the covenants (of security and safeguard enjoyed) by the Quraish,

2. Their covenants (covering) journeys by winter and summer,-

3. Let them adore the Lord of this House,

4. Who provides them with food against hunger, and with security against fear (of danger).

Basically:

1. God holy book Quran that had been revealed to prophet Muhammad (peace be upon him) through the angel Gabriel (or Jibril), and
2. Sunnah that is all prophet Muhammad sayings and practices

- Seeking knowledge is a sacred duty. It's assured A LOT in the Islamic teachings, both the holy Quran & the Sunnah of the prophet Muhammad PBUH.

As the question requires a clarification in the light of the holy Quran, then these are examples:

• The first word revealed of the Quran was the word "Iqraa" which is translated into "read" or "educate yourself".

( Proclaim! (or read!) in the name of thy Lord and Cherisher, Who created-

2. Created man, out of a (mere) clot of congealed blood:

3. Proclaim! And thy Lord is Most Bountiful,-

4. He Who taught (the use of) the pen,-

5. Taught man that which he knew not).

Yes. You'll find it in sura 33, ayat 37. Zaid's patronymic, "bin Haris", is not mentioned, but the person referred to is definitely Zaid bin Haris. The ayat reads:

"And when you said to him on whom Allah has bestowed grace and you have done a favour: 'Keep your wife to yourself, and have fear of Allah,' but you did hide in yourself that which Allah will make manifest, you did fear the people; whereas Allah had a better right that you should fear Him. So, when Zayd had completed his aim with her, We gave her to you in marriage, so that there may be no difficulty to the believers in respect of the wives of their adopted sons when the latter have no desire to keep them. And Allah's command must be fulfilled."

This is what the great Sunni scholar Ibn Kathir says about the situation.

"Allah tells what His Prophet said to his freed slave Zayd bin Harithah, who was the one on whom Allah had bestowed grace, i.e., through Islam and following the Messenger. 'And you have done a favour to him' means 'by freeing him from slavery.' And he was a great leader, held in high esteem and beloved by the Prophet . He was known as 'the beloved', and his son Usamah was known as 'the beloved son of the beloved'. `A'ishah [Muhammad's wife] said: 'The Messenger of Allah never sent him on a campaign but he appointed him as its commander, and if he had lived after him he would have appointed him as his successor.'

"The Messenger of Allah had given him [Zayd] in marriage to his [Muhammad's] cousin, Zaynab bint Jahsh Al-Asadiyyah. Allah says: 'But you did hide in yourself that which Allah will make manifest, you did fear the people whereas Allah had a better right that you should fear Him.' `A'ishah said, "If Muhammad were to have concealed anything that was revealed to him of the Book of Allah, he would have concealed this Ayah.'

"'So, when Zayd had completed his aim with her, We gave her to you in marriage,' meaning, 'When her marriage to Zayd was over and he had separated from her, We married her to you,' and the One Who was her guardian in this marriage was Allah Himself, in the sense that He revealed to the Prophet that he should go in unto her without any guardian, contractual agreement, dower or witnesses among mankind.

"When Zaynab's waiting-period [after divorce] finished, the Messenger of Allah said to Zayd bin Harithah, 'Go to her and tell her about me (that I want to marry her).' So, he went to her and found her kneading dough. He (Zayd) said, `When I saw her I felt such respect for her that I could not even look at her and tell her what the Messenger of Allah had said, so I turned my back to her and stepped aside, and said, "O Zaynab! Rejoice, for the Messenger of Allah has sent me to propose marriage to you on his behalf." She said, "I will not do anything until I pray to my Lord, may He be glorified." So she went to the place where she usually prayed. Then Qur'an was revealed and the Messenger of Allah came and entered without permission.'"

"Zaynab bint Jahsh used to boast to the other wives of the Prophet , saying, 'Your families arranged your marriages, but Allah arranged my marriage from above the seven heavens.'''

"'So that there may be no difficulty to the believers in respect of the wives of their adopted sons when the latter have no desire to keep them' means, 'We permitted you to marry her, and We did that so that there would no longer be any difficulty for the believers with regard to their marrying the ex-wives of their adopted sons.' Before prophethood, the Messenger of Allah had adopted Zayd bin Harithah, and he was known as Zayd, the son of Muhammad. Allah put a stop to this when He said: 'Nor has He made your adopted sons your real sons … Call them after their fathers, that is more just with Allah' (33:4-5). Then this was confirmed and made even clearer by the marriage of the Messenger of Allah to Zaynab bint Jahsh, when Zayd bin Harithah divorced her.

"'And Allah's command must be fulfilled' means, 'this that has happened was decreed by Allah and was inevitable.' Allah knew that Zaynab would become one of the wives of the Prophet."
