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  

There was revealed: 'Not equal are those believers who sit (at home) and those who strive and fight in the Cause of Allah.' (4.95) The Prophet ﷺ said, "Call Zaid for me and let him bring the board, the inkpot and the scapula bone (or the scapula bone and the ink pot)."' Then he said, "Write: 'Not equal are those Believers who sit..", and at that time ʿAmr bin Um Maktum, the blind man was sitting behind the Prophet ﷺ . He said, "O Allah's Apostle! What is your order For me (as regards the above Verse) as I am a blind man?" So, instead of the above Verse, the following Verse was revealed: 'Not equal are those believers who sit (at home) except those who are disabled (by injury or are blind or lame etc.) and those who strive and fight in the cause of Allah.' (4.95)  

لَمَّا نَزَلَتْ {لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ وَالْمُجَاهِدُونَ فِي سَبِيلِ اللَّهِ} قَالَ النَّبِيُّ ﷺ ادْعُ لِي زَيْدًا وَلْيَجِئْ بِاللَّوْحِ وَالدَّوَاةِ وَالْكَتِفِ أَوِ الْكَتِفِ وَالدَّوَاةِ ثُمَّ قَالَ اكْتُبْ لاَ يَسْتَوِي الْقَاعِدُونَ وَخَلْفَ ظَهْرِ النَّبِيِّ ﷺ عَمْرُو بْنُ أُمِّ مَكْتُومٍ الأَعْمَى قَالَ يَا رَسُولَ اللَّهِ فَمَا تَأْمُرُنِي فَإِنِّي رَجُلٌ ضَرِيرُ الْبَصَرِ فَنَزَلَتْ مَكَانَهَا {لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ} فِي سَبِيلِ اللَّهِ {غَيْرُ أُولِي الضَّرَرِ}
