"When the following was revealed: 'Not equal are those of the believers who sit (4:95)' 'Amr bin Umm Maktum came to the Prophet ﷺ." He said: "He was blind, so he said: 'O Messenger of Allah! What do you order me with? Indeed my vision is disabled.' So Allah [Most High] revealed this Ayah: 'Except those who are disabled.' So the Prophet ﷺ said: 'Bring me a shoulder bone and inkwell' - or 'Bring me a tablet and an inkwell.'"
لَمَّا نَزَلَتْ (لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ ) جَاءَ عَمْرُو ابْنُ أُمِّ مَكْتُومٍ إِلَى النَّبِيِّ ﷺ قَالَ وَكَانَ ضَرِيرَ الْبَصَرِ فَقَالَ يَا رَسُولَ اللَّهِ مَا تَأْمُرُنِي إِنِّي ضَرِيرُ الْبَصَرِ فَأَنْزَلَ اللَّهُ تَعَالَى هَذِهِ الآيَةَ ( غَيْرُ أُولِي الضَّرَرِ ) الآيَةَ فَقَالَ النَّبِيُّ ﷺ ائْتُونِي بِالْكَتِفِ وَالدَّوَاةِ أَوِ اللَّوْحِ وَالدَّوَاةِ
