Zayd bin Thabit reported,

When we were copying the pages into official codices, I could not find one verse from Surah al-Ahzab that I had often heard the Messenger of Allah ﷺ reciting. I did not find it with anyone except Khuzaymah al-Ansari, the one whose testimony the Messenger of Allah ﷺ had declared equal to the testimony of two men. The verse was "Among the believers are men who have been true to their covenant with Allah" [Ahzab 33:23].
