When we collected the fragramentary manuscripts of the Quran into copies, I missed one of the
Verses of Surat al-Ahzab which I used to hear Allah's Messenger (ﷺ) reading. Finally I did not find it with
anybody except Khuza`ima Al-Ansari, whose witness was considered by Allah's Messenger (ﷺ) equal to the
witness of two men. (And that Verse was:)
'Among the believers are men who have been true to their covenant with Allah.'
Sahih al-Bukhari Book 65, Hadith 306
