It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that Sayyiduna Hudhayfah bin al-Yaman (may Allah be pleased with him) came to Sayyiduna Uthman bin Affan (may Allah be pleased with him). At that time he was engaged in jihad together with the people of Syria and the people of Iraq for the conquest of Armenia and Azerbaijan. The different ways in which people recited the Qur'an (differences in recitation) had greatly alarmed Sayyiduna Hudhayfah (may Allah be pleased with him), so Sayyiduna Hudhayfah (may Allah be pleased with him) said to Sayyiduna Uthman (may Allah be pleased with him): "O Commander of the Believers! Take care of this Ummah before they differ over the Book of Allah as the Jews and Christians differed." Thereupon Sayyiduna Uthman (may Allah be pleased with him) sent a message to the Mother of the Believers, Sayyidah Hafsah (may Allah be pleased with her): "Send us the sheets (the Qur'anic manuscripts) so that we may copy them in the form of a mushaf; then we will return them to you." Sayyidah Hafsah (may Allah be pleased with her) sent the sheets to Sayyiduna Uthman (may Allah be pleased with him). Then Sayyiduna Uthman (may Allah be pleased with him) gave the order to Sayyiduna Zayd bin Thabit, Sayyiduna Abdullah bin al-Zubayr, Sayyiduna Sa'id bin al-As and Sayyiduna Abd al-Rahman bin al-Harith bin Hisham (may Allah be pleased with them), and they copied those sheets into mushafs. Sayyiduna Uthman (may Allah be pleased with him) said to those three men of Quraysh: "When you and Zayd bin Thabit differ over the writing of any word of the Qur'an, write it in the language of Quraysh, for the Qur'an was revealed in their language." So they did that. When all the sheets had been copied and the mushafs were ready, Sayyiduna Uthman (may Allah be pleased with him) returned the original sheets to Sayyidah Hafsah (may Allah be pleased with her), sent one mushaf to every corner of the Islamic realm, and ordered that all other sheets or copies of the Qur'an that people had besides these should be erased or burnt. Imam al-Zuhri (may Allah have mercy on him) said: Kharijah bin Zayd bin Thabit (may Allah have mercy on him) informed me that he heard Sayyiduna Zayd bin Thabit (may Allah be pleased with him) say: "When we were copying the mushafs, I could not find a verse of Surah al-Ahzab, although I used to hear the Messenger of Allah (peace and blessings be upon him) recite it myself. I searched for it and found it with Sayyiduna Khuzaymah bin Thabit al-Ansari (may Allah be pleased with him): 'Among the believers are men who have been true to the covenant they made with Allah.' So I added it to its surah in the mushaf."
