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}  

[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  

[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»  

"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".
