Sahih Bukhari Volume 6, Book 66, Hadith 4991

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، أَنَّ ابْنَ السَّبَّاقِ، قَالَ إِنَّ زَيْدَ بْنَ ثَابِتٍ قَالَ أَرْسَلَ إِلَىَّ أَبُو بَكْرٍ ـ رضى الله عنه ـ قَالَ إِنَّكَ كُنْتَ تَكْتُبُ الْوَحْىَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم فَاتَّبِعِ الْقُرْآنَ‏.‏ فَتَتَبَّعْتُ حَتَّى وَجَدْتُ آخِرَ سُورَةِ التَّوْبَةِ آيَتَيْنِ مَعَ أَبِي خُزَيْمَةَ الأَنْصَارِيِّ لَمْ أَجِدْهُمَا مَعَ أَحَدٍ غَيْرَهُ ‏{‏لَقَدْ جَاءَكُمْ رَسُولٌ مِنْ أَنْفُسِكُمْ عَزِيزٌ عَلَيْهِ مَا عَنِتُّمْ‏}‏ إِلَى آخِرِهَا

Narrated By Zaid bin Thabit : Abu Bakr sent for me and said, "You used to write the Divine Revelations for Allah's Apostle : So you should search for (the Qur'an and collect) it." I started searching for the Qur'an till I found the last two Verses of Surat At-Tauba with Abi Khuzaima Al-Ansari and I could not find these Verses with anybody other than him. (They were): 'Verily there has come unto you an Apostle (Muhammad) from amongst yourselves. It grieves him that you should receive any injury or difficulty...' (9.128-129)
