These suhuf were with Abu Bakr till his death, then with `Umar as long as he was alive, and then with his daughter Hafsah."2 Ibn Abi Dawad reports the following tradition transmitted through a hasan chain: `Umar enquired about a certain Quranic verse and he was told that it was with a person killed in the battle of Yamamah. Thereupon he said "Inna lillah," and ordered the collection of the Qur'an.
Thus he was the first one to compile it in form of a mushaf (codex).3 Ibn Ashtah in al-Masahif, narrates the following from Ibn Buraydah: Ibn Buraydah said: "The first person to collect the Qur'an in the form of a mushaf was Salim, the mawla of Hudhayfah. He had taken an oath not to put on his cloak (i.e. to leave his home) until he had collected the Qur'an.
Then they consulted as to what they would call it, and some of them suggested that it be named 'al-sifr.' Salim observed that this name was given by the Jews, (to their scripture), and therefore they did not favour it.
Then he said: 'I have seen the like of it being called `mushaf in Abyssinia.' Thereupon they concurred on naming it al-mushaf4 Al-Bukhari also reports the following tradition, which has also been recorded by al-Tirmidhi: Zayd ibn Thabit said: "When we wrote the masahif and I missed a verse I used to hear from the Prophet (S). I found it later with Abu. Khuzayrnah al'Ansari: من المؤمنين رجال صدقوا... (33:23).
`Umar did not use to accept a verse of the Book of God unless two men gave evidence of its being so. A man belonging- to the Ansar came with two verses and `Umar said to him: 'I will not demand apart from yourself another witness for it.' "5 Yahya ibn ‘Abd al-Rahman Hatib observes: " `Umar decided to collect the Qur'an and standing up among the people he said: 'Anyone who has received anything of the Qur'an from the Prophet (S) should bring it to us.' They had written it on paper, stone tablets and palm leaves, and nothing used to be accepted from them unless two witnesses gave evidence to this effect.
Then Khuzaymah came and said: 'I see that you have not included two verses and not written them.' Umar enquired: 'What are those two?' He replied: 'I have received from the Prophet (S): لقد جاءكم رسول.. (9:128):6 Anas ibn Malik said: "I was one of those who were being dictated the Qur'an. At times when they differed regarding a verse, they would recall someone who had heard it from the Prophet (S). At times that person would be absent or in some remote place.
