Narrated Al-Bara:

When the Verse:-- "Not equal are those of the believers who sit (at home)" (4:95) was revealed, Allah Messenger called for Zaid who wrote it. In the meantime Ibn Um Maktum came and complained of his blindness, so Allah revealed: "Except those who are disabled (by injury or are blind or lame..." etc.) (4:95)

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ ـ رضى الله عنه ـ قَالَ لَمَّا نَزَلَتْ ‏{‏لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ‏}‏ دَعَا رَسُولُ اللَّهِ صلى الله عليه وسلم زَيْدًا فَكَتَبَهَا، فَجَاءَ ابْنُ أُمِّ مَكْتُومٍ فَشَكَا ضَرَارَتَهُ، فَأَنْزَلَ اللَّهُ ‏{‏غَيْرَ أُولِي الضَّرَرِ‏}‏
