Sahih (Sahih al-Bukhari)
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}
Narrated Al-Bara:When the Verse:-- "Not equal are those of the believers who sit (at home)" (4.95) was revealed, Allah's Apostle 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)
