"Sahl bin Sa'd said: 'I saw Marwan sitting in the Masjid so I went and sat beside him, and he told us that Zaid bin Thabit had told him, that the Messenger of Allah ﷺ dictated to him the words: [Not equal are those of the believers who sit (at home) and those who strive hard and fight in the cause of Allah]. Then Ibn umm Maktum came to him while he was dictating it to me (Zaid) and said: 'O Messenger of Allah! If I were able to go for Jihad I would go out for Jihad.' But he was a blind man. Then Allah revealed to His Messenger ﷺ - while his thigh was agaisnt my thigh, and (it became so heavy that) I thought my thigh would break, then it was lifted from him, and Allah, the Mighty and Sublime, revealed: 'Except those who are disabled (by injury or are blind or lame).'" [1] [1] An-Nisa' 4:95. (Using translation from Nasāʾī 3100)
رَأَيْتُ مَرْوَانَ جَالِسًا فِي الْمَسْجِدِ فَأَقْبَلْتُ حَتَّى جَلَسْتُ إِلَى جَنْبِهِ فَأَخْبَرَنَا أَنَّ زَيْدَ بْنَ ثَابِتٍ أَخْبَرَهُ أَنَّ رَسُولَ اللهِ ﷺ أَمْلَى عَلَيَّ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ وَالْمُجَاهِدُونَ فِي سَبِيلِ اللهِ} قَالَ فَجَاءَهُ ابْنُ أُمِّ مَكْتُومٍ وَهُوَ يُمِلُّهَا عَلَيَّ فَقَالَ يَا رَسُولَ اللهِ وَاللهِ لَوْ أَسْتَطِيعُ الْجِهَادَ لَجَاهَدْتُ وَكَانَ رَجُلًا أَعْمَى فَأَنْزَلَ اللهُ عَلَى رَسُولِهِ ﷺ وَفَخِذُهُ عَلَى فَخِذِي فَثَقُلَتْ حَتَّى هَمَّتْ تُرَضُّ فَخِذِي ثُمَّ سُرِّيَ عَنْهُ فَأَنْزَلَ اللهُ {غَيْرُ أُولِي الضَّرَرِ} [النساء 95]
