Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))

"Of them, some have fulfilled their obligations (i.e ., have been martyred) and some of them are still waiting, but they have never changed (i.e., they never proved treacherous to their covenant which they concluded with Allah) in the least." (V.33:23)

Sahih al-Bukhari 4784

Narrated Zaid bin Thabit:

When we collected the fragramentary manuscripts of the Qur'an 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.'

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي خَارِجَةُ بْنُ زَيْدِ بْنِ ثَابِتٍ، أَنَّ زَيْدَ بْنَ ثَابِتٍ، قَالَ لَمَّا نَسَخْنَا الصُّحُفَ فِي الْمَصَاحِفِ فَقَدْتُ آيَةً مِنْ سُورَةِ الأَحْزَابِ، كُنْتُ أَسْمَعُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقْرَؤُهَا، لَمْ أَجِدْهَا مَعَ أَحَدٍ إِلاَّ مَعَ خُزَيْمَةَ الأَنْصَارِيِّ، الَّذِي جَعَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم شَهَادَتَهُ شَهَادَةَ رَجُلَيْنِ ‏{‏مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ‏}
