Abu Bakr sent for me and said, "You used to write the Divine Revelations for Messenger of Allah ﷺ : 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 Khuzaʿima 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)
أَرْسَلَ إِلَىَّ أَبُو بَكْرٍ ؓ قَالَ إِنَّكَ كُنْتَ تَكْتُبُ الْوَحْىَ لِرَسُولِ اللَّهِ ﷺ 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 آخِرِهِ
