It was narrated that Al-Bara' said:

"When the following was revealed: 'Not equal are those of the believers who sit (at home),' Ibn Umm Maktum, who was blind, came and said: 'O Messenger of Allah, what about me? I am blind.' He said: 'He did not leave before the following was revealed: Except those who are disabled (by injury or are blind or lame).'" [Surah an-Nisaa 4:95]

أَخْبَرَنَا مُحَمَّدُ بْنُ عُبَيْدٍ، قَالَ حَدَّثَنَا أَبُو بَكْرِ بْنُ عَيَّاشٍ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، قَالَ لَمَّا نَزَلَتْ { لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ } جَاءَ ابْنُ أُمِّ مَكْتُومٍ وَكَانَ أَعْمَى فَقَالَ يَا رَسُولَ اللَّهِ فَكَيْفَ فِيَّ وَأَنَا أَعْمَى قَالَ فَمَا بَرِحَ حَتَّى نَزَلَتْ { غَيْرُ أُولِي الضَّرَرِ } .
