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}  

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 Messenger of Allah ﷺ reading. Finally I did not find it with anybody except Khuzaʿima Al-Ansari, whose witness was considered by Messenger of Allah 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.'  

لَمَّا نَسَخْنَا الصُّحُفَ فِي الْمَصَاحِفِ فَقَدْتُ آيَةً مِنْ سُورَةِ الأَحْزَابِ كُنْتُ أَسْمَعُ رَسُولَ اللَّهِ ﷺ يَقْرَؤُهَا لَمْ أَجِدْهَا مَعَ أَحَدٍ إِلاَّ مَعَ خُزَيْمَةَ الأَنْصَارِيِّ الَّذِي جَعَلَ رَسُولُ اللَّهِ ﷺ شَهَادَتَهُ شَهَادَةَ رَجُلَيْنِ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ}  

[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] Zaid bin Thabit, when we were writing the Mus'haf, I lost a verse that I used to hear from the Messenger of Allah ﷺ . So, I found it with Khuzaymah bin Thabit al-Ansari, "Among the believers are men who have been true to their covenant with Allah; of them, some have fulfilled their obligations and some are still waiting, but they have never changed their determination." He (Zaid bin Thabit) said, "Khuzaymah was known as 'Dhul-Shahadatayn' (possessing two testimonies)."  

زَيْدُ بْنُ ثَابِتٍ لَمَّا كَتَبْنَا الْمَصَاحِفَ فَقَدْتُ آيَةً كُنْتُ أَسْمَعُهَا مِنْ رَسُولِ اللهِ ﷺ فَوَجَدْتُهَا عِنْدَ خُزَيْمَةَ بْنِ ثَابِتٍ الْأَنْصَارِيِّ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللهَ عَلَيْهِ فَمِنْهُمْ مَنْ قَضَى نَحْبَهُ وَمِنْهُمْ مَنْ يَنْتَظِرُ وَمَا بَدَّلُوا تَبْدِيلًا} قَالَ «وَكَانَ خُزَيْمَةُ يُدْعَى ذُو الشَّهَادَتَيْنِ»  

[Machine] Zaid, when we wrote the copies of the Quran, I lost a verse that I used to hear from the Messenger of Allah ﷺ . I found it with Khuzaimah bin Thabit al-Ansari, who was called "the one with the two testimonies." The verse is: "Among the believers are men who have been true to their covenant with Allah. Some of them have fulfilled their vow, and some are still waiting, but they have not changed (their commitment) in the least."  

زَيْدٌ لَمَّا كَتَبْنَا الْمَصَاحِفَ فَقَدْتُ آيَةً كُنْتُ أَسْمَعُهَا مِنْ رَسُولِ اللهِ ﷺ فَوَجَدْتُهَا عِنْدَ خُزَيْمَةَ بْنِ ثَابِتٍ الْأَنْصَارِيِّ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللهَ عَلَيْهِ فَمِنْهُمْ مَنْ قَضَى نَحْبَهُ وَمِنْهُمْ مَنْ يَنْتَظِرُ وَمَا بَدَّلُوا تَبْدِيلًا} قَالَ «وَكَانَ خُزَيْمَةُ يُدْعَى ذَا الشَّهَادَتَيْنِ»  

"لَمَّا كَتَبْنَا الْمَصَاحِفَ فُقِدَ آيَةٌ كُنْتُ أَسْمَعُهَا مِنْ رَسُولِ الله ﷺ ، فَوَجَدْتُهَا عِنْدَ خُزَيْمَةَ بن ثَابِتٍ {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ ... } إِلَى { ... تَبْدِيلًا}، وَكَانَ خُزَيْمَةُ يُدعَى: (ذَا الشَّهَادَتَيْنِ)، أَجَازَ رسُولُ الله ﷺ شَهَادَتَهُ بِشَهَادَةِ رَجُلَيْنِ".  

"عَنْ زَيْدِ بْنِ ثَابِتٍ قَالَ؟ فَقَدتُ آيَةً كُنْتُ أَسْمَعُهَا مِنْ رَسُولِ الله ﷺ لَمَّا كُتِبَ الْمَصَاحِفُ فَوَجَدتُّهَا مَعَ خُزَيْمَةَ بْنِ ثَابِتٍ، وَكَانَ خُزيْمَةُ يُدْعَى ذَا الشَّهَادَتَيْنِ: {مِنَ الْمُؤْمِنِينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللَّهَ عَلَيْهِ ... } الآية".
