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 Messenger of Allah ﷺ reciting. I could not find it except with Khuzaʿima bin Thabjt Al-Ansari, whose witness Messenger of Allah 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)  

نَسَخْتُ الصُّحُفَ فِي الْمَصَاحِفِ فَفَقَدْتُ آيَةً مِنْ سُورَةِ الأَحْزَابِ كُنْتُ أَسْمَعُ رَسُولَ اللَّهِ ﷺ يَقْرَأُ بِهَا فَلَمْ أَجِدْهَا إِلاَّ مَعَ خُزَيْمَةَ بْنِ ثَابِتٍ الأَنْصَارِيِّ الَّذِي جَعَلَ رَسُولُ اللَّهِ ﷺ شَهَادَتَهُ شَهَادَةَ رَجُلَيْنِ وَهْوَ قَوْلُهُ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ}  

'Among the Believers are men who have been true in their covenant with Allah.' (33.23)  

فَقَدْتُ آيَةً مِنَ الأَحْزَابِ حِينَ نَسَخْنَا الْمُصْحَفَ قَدْ كُنْتُ أَسْمَعُ رَسُولَ اللَّهِ ﷺ يَقْرَأُ بِهَا فَالْتَمَسْنَاهَا فَوَجَدْنَاهَا مَعَ خُزَيْمَةَ بْنِ ثَابِتٍ الأَنْصَارِيِّ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ} فَأَلْحَقْنَاهَا فِي سُورَتِهَا فِي الْمُصْحَفِ  

[Machine] "When we made copies of the Qur'an, a verse from Surah Al-Ahzab was lost. I used to hear the Prophet ﷺ recite it, so I searched for it but couldn't find it with anyone except Khuzayma ibn Thabit, the Ansari, who the Messenger of Allah ﷺ made his testimony equal to that of two men. The verse is the saying of Allah ﷻ {Among the believers are men who have been true to their covenant with Allah} [Al-Ahzab 23]."  

لَمَّا نَسَخْنَا الْمَصَاحِفَ فُقِدَتْ آيَةٌ مِنْ سُورَةِ الْأَحْزَابِ قَدْ كُنْتُ أَسْمَعُ النَّبِيَّ ﷺ يَقْرَأُ بِهَا فَالْتَمَسْتُهَا فَلَمْ أَجِدْهَا مَعَ أَحَدٍ إِلَّا مَعَ خُزَيْمَةَ بْنِ ثَابِتٍ الْأَنْصَارِيِّ الَّذِي جَعَلَ رَسُولُ اللهِ ﷺ شَهَادَتَهُ شَهَادَةَ رَجُلَيْنِ قَوْلُ اللهِ ﷻ{مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللهَ عَلَيْهِ} [الأحزاب 23]  

[Machine] When the Qur'ans were written, I lost a verse that I used to hear from the Messenger of Allah ﷺ . I found it with Khuzaymah al-Ansari from the believers, who said, "Men who have fulfilled their covenant with Allah." [Quran 33:23] until "for another." [Quran 33:23] Khuzaymah, also known as Dhu al-Shahadatayn, was granted the testimony of his testimony by the Messenger of Allah ﷺ with the testimony of two men. Al-Zuhri said that he was killed on the day of Siffin along with Ali.  

لَمَّا كُتِبَتِ الْمَصَاحِفُ فَقَدْتُ آيَةً كُنْتُ أَسْمَعُهَا مِنْ رَسُولِ اللهِ ﷺ فَوَجَدْتُهَا عِنْدَ خُزَيْمَةَ الْأَنْصَارِيِّ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللهَ عَلَيْهِ} [الأحزاب 23] إِلَى {تَبْدِيلًا} [الأحزاب 23] قَالَ فَكَانَ خُزَيْمَةُ يُدْعَى ذَا الشَّهَادَتَيْنِ أَجَازَ رَسُولُ اللهِ ﷺ شَهَادَتَهُ بِشَهَادَةِ رَجُلَيْنِ قَالَ الزُّهْرِيُّ وَقُتِلَ يَوْمَ صِفِّينَ مَعَ عَلِيٍّ  

'Among the Believers are men who have been true in their covenant with Allah.' (33.23) (Using translation from Bukhārī 4988)   

فَقَدْتُ آيَةً مِنْ سُورَةِ الْأَحْزَابِ حِينَ نَسَخْنَا الْمُصْحَفَ كُنْتُ أَسْمَعُ رَسُولَ اللهِ ﷺ يَقْرَؤُهَا فَوَجَدْتُهَا مَعَ خُزَيْمَةَ بْنِ ثَابِتٍ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللهَ عَلَيْهِ} [الأحزاب 23] فَأَلْحَقْتُهَا فِي سُورَتِهَا فِي الْمُصْحَفِ
