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 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.) (4:95)
