Narrated Kharija bin Zaid:
حَدَّثَنَا أَبُو الْيَمَانِ ، أَخْبَرَنَا شُعَيْبٌ ، عَنِ الزُّهْرِيِّ ، حَدَّثَنِي إِسْمَاعِيلُ ، قَالَ حَدَّثَنِي أَخِي ، عَنْ سُلَيْمَانَ ، أُرَاهُ عَنْ مُحَمَّدِ بْنِ أَبِي عَتِيقٍ ، عَنِ ابْنِ شِهَابٍ ، عَنْ خَارِجَةَ بْنِ زَيْدٍ ، أَنَّ زَيْدَ بْنَ ثَابِتٍ ـ رضى الله عنه ـ قَالَ نَسَخْتُ الصُّحُفَ فِي الْمَصَاحِفِ، فَفَقَدْتُ آيَةً مِنْ سُورَةِ الأَحْزَابِ، كُنْتُ أَسْمَعُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقْرَأُ بِهَا، فَلَمْ أَجِدْهَا إِلاَّ مَعَ خُزَيْمَةَ بْنِ ثَابِتٍ الأَنْصَارِيِّ الَّذِي جَعَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم شَهَادَتَهُ شَهَادَةَ رَجُلَيْنِ، وَهْوَ قَوْلُهُ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ}
Zaid bin Thabit said, "When the Qur'an was compiled from various written manuscripts, one of the Verses of Surat Al-Ahzab was missing which I used to hear Allah's Messenger (ﷺ) reciting. I could not find it except with Khuza`ima bin Thabjt Al-Ansari, whose witness Allah's Messenger (ﷺ) regarded as equal to the witness of two men. And the Verse was:-- "Among the believers are men who have been true to what they covenanted with Allah." (33.23)
