Sahih al-Bukhari 2831
Narrated Al-Bara:
When the Divine Inspiration: "Those of the believers who sit (at home), was revealed the Prophet (ﷺ) sent 
for Zaid (bin Thabit) who came with a shoulder-blade and wrote on it. Ibn Um-Maktum complained 
about his blindness and on that the following revelation came: "Not equal are those believers who sit 
(at home) except those who are disabled (by injury, or are blind or lame etc.) and those who strive 
hard and fight in the Way of Allah with their wealth and lives)." (4.95)
حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، قَالَ سَمِعْتُ الْبَرَاءَ ـ رضى الله عنه ـ يَقُولُ لَمَّا نَزَلَتْ ‏{‏لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ‏}‏ دَعَا رَسُولُ اللَّهِ صلى الله عليه وسلم زَيْدًا، فَجَاءَ بِكَتِفٍ فَكَتَبَهَا، وَشَكَا ابْنُ أُمِّ مَكْتُومٍ ضَرَارَتَهُ فَنَزَلَتْ ‏{‏لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ غَيْرُ أُولِي الضَّرَرِ ‏}‏‏.‏
