It was narrated that Al-Bara' said: "When the following was revealed: 'Not equal are those of the believers who sit (at home),' [1] 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).'" [2] [1] An-Nisa' 4: 95. [2] An-Nisa' 4: 95.
