1. Narrated Abu Sa`id Al-Mu'alla: While I was praying, the Prophet ( pbuh ) called me but I did not respond to his call. Later I said, "O Allah's Apostle! I was praying." He said, "Didn't Allah say: 'O you who believe! Give
your response to Allah (by obeying Him) and to His Apostle when he calls you'?" (8.24) He then said, "Shall I not teach you the most superior Surah in the Qur'an?" He said, '(It is), 'Praise be to Allah, the Lord of the worlds. ' (i.e., Surat Al-Fatiha) which consists of seven repeatedly recited Verses and the Magnificent Qur'an which was given to me."
(Bukhari)
2. Narrated `Abdullah (bin Mas`ud):
By Allah other than Whom none has the right to be worshipped! There is no Sura revealed in Allah's Book but I know at what place it was revealed; and there is no Verse revealed in Allah's Book but I know about whom it was revealed. And if I know that there is somebody who knows Allah's Book better than I, and he is at a place that camels can reach, I would go to him.
(Bukhari)
3. Narrated Masriq: `Abdullah bin `Amr mentioned `Abdullah bin Masud and said, "I shall ever love that man, for I heard the Prophet ( pbuh ) saying, 'Take (learn) the Qur'an from four: `Abdullah bin Masud, Salim, Mu`adh and Ubai bin Ka`b.' "
(Bukhari)
4. Gabriel used to repeat the recitation of the Qur'an with the Prophet ( pbuh ) once a year, but he repeated it twice with him in the year he died. The Prophet ( pbuh ) used to stay in I`tikaf for ten days every year (in the month of Ramadan), but in the year of his death, he stayed in I`tikaf for twenty days.
(Bukhari)
5. Narrated `Abdullah bin `Abbas: Allah's Messenger ( pbuh ) said, "Gabriel recited the Qur'an to me in one way. Then I requested him (to read it in another way), and continued asking him to recite it in other ways, and he recited it in several ways till he ultimately recited it in seven different ways."
(Bukhari)
6. Narrated Anas bin Malik: Hudhaifa bin Al-Yaman came to `Uthman at the time when the people of Sham and the people of Iraq were Waging war to conquer Arminya and Adharbijan. Hudhaifa was afraid of their (the people of Sham and Iraq) differences in the recitation of the Qur'an, so he said to `Uthman, "O chief of the Believers! Save this nation before they differ about the Book (Qur'an) as Jews and the Christians did before." So `Uthman sent a message to Hafsa saying, "Send us the manuscripts of the Qur'an so that we may compile the Qur'anic materials in perfect copies and return the manuscripts to you." Hafsa sent it to `Uthman. `Uthman then ordered Zaid bin Thabit, `Abdullah bin AzZubair, Sa`id bin Al-As and `AbdurRahman bin Harith bin Hisham to rewrite the manuscripts in perfect copies. `Uthman said to the three Quraishi men, "In case you disagree with Zaid bin Thabit on any point in the Qur'an, then write it in the dialect of Quraish, the Qur'an was revealed in their tongue." They did so, and when they had written many copies, `Uthman returned the original manuscripts to Hafsa. `Uthman sent to every Muslim province one copy of what they had copied, and ordered that all the other Qur'anic materials, whether written in fragmentary manuscripts or whole copies, be burnt.
(Bukhari)
7. Narrated Zaid bin Thabit: Abu Bakr As-Siddiq sent for me when the people! of Yamama had been killed (i.e., a number of the Prophet's Companions who fought against Musailama). (I went to him) and found `Umar bin Al- Khattab sitting with him. Abu Bakr then said (to me), "`Umar has come to me and said: "Casualties were heavy among the Qurra' of the! Qur'an (i.e. those who knew the Qur'an by heart) on the day of the Battle of Yalmama, and I am afraid that more heavy casualties may take place among the Qurra' on other battlefields, whereby a large part of the Qur'an may be lost. Therefore I suggest, you (Abu Bakr) order that the Qur'an be collected." I said to `Umar, "How can you do something which Allah's Apostle did not do?" `Umar said, "By Allah, that is a good project. "`Umar kept on urging me to accept his proposal till Allah opened my chest for it and I began to realize the good in the idea which `Umar had realized." Then Abu Bakr said (to me). 'You are a wise young man and we do not have any suspicion about you, and you used to write the Divine Inspiration for Allah's Messenger ( pbuh ). So you should search for (the fragmentary scripts of) the Qur'an and collect it in one book)." By Allah If they had ordered me to shift one of the mountains, it would not have been heavier for me than this ordering me to collect the Qur'an. Then I said to Abu Bakr, "How will you do something which Allah's Messenger ( pbuh ) did not do?" Abu Bakr replied, "By Allah, it is a good project." Abu Bakr kept on urging me to accept his idea until Allah opened my chest for what He had opened the chests of Abu Bakr and `Umar. So I started looking for the Qur'an and collecting it from (what was written on) palmed stalks, thin white stones and also from the men who knew it by heart, till I found the last Verse of Surat at-Tauba (Repentance) with Abi Khuza`ima Al-Ansari, and I did not find it with anybody other than him. The Verse is: 'Verily there has come unto you an Apostle (Muhammad) from amongst yourselves. It grieves him that you should receive any injury or difficulty..(till the end of Surat-Baraa' (at-Tauba) (9.128-129) Then the complete manuscripts (copy) of the Qur'an remained with Abu Bakr till he died, then with `Umar till the end of his life, and then with Hafsa, the daughter of `Umar.
(Bukhari)
8. Narrated Anas bin Malik: The Caliph `Uthman ordered Zaid bin Thabit, Sa`id bin Al-As, `Abdullah bin Az-Zubair and `Abdur- Rahman bin Al-Harith bin Hisham to write the Qur'an in the form of a book (Mushafs) and said to them. "In case you disagree with Zaid bin Thabit (Al-Ansari) regarding any dialectic Arabic utterance of the Qur'an, then write it in the dialect of Quraish, for the Qur'an was revealed in this dialect." So they did it.
(Bukhari)
9. Narrated Jundub: Once the Prophet ( pbuh ) fell ill and did not offer the night prayer (Tahajjud prayer) for a night or two. A woman (the wife of Abu Lahab) came to him and said, "O Muhammad ! I do not see but that your Satan has left you." Then Allah revealed (Surat-Ad-Duha): 'By the fore-noon, and by the night when it darkens (or is still); Your Lord has not forsaken you, nor hated you.'
(Bukhari)
10. Narrated Abu Huraira: The Prophet ( pbuh ) said, "Every Prophet was given miracles because of which people believed, but what I have been given, is Divine Inspiration which Allah has revealed to me. So I hope that my followers will outnumber the followers of the other Prophets on the Day of Resurrection."
(Bukhari)
11. Narrated `Aisha and Ibn `Abbas: The Prophet ( pbuh ) remained in Mecca for ten years, during which the Qur'an used to be revealed to him; and he stayed in Medina for ten years.(Bukhari)
