حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ الزُّهْرِيُّ، قَالَ حَدَّثَنِي صَالِحُ بْنُ كَيْسَانَ، عَنِ ابْنِ شِهَابٍ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ، أَنَّهُ قَالَ رَأَيْتُ مَرْوَانَ بْنَ الْحَكَمِ جَالِسًا فِي الْمَسْجِدِ، فَأَقْبَلْتُ حَتَّى جَلَسْتُ إِلَى جَنْبِهِ، فَأَخْبَرَنَا أَنَّ زَيْدَ بْنَ ثَابِتٍ أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَمْلَى عَلَيْهِ لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ وَالْمُجَاهِدُونَ فِي سَبِيلِ اللَّهِ قَالَ فَجَاءَهُ ابْنُ أُمِّ مَكْتُومٍ وَهُوَ يُمِلُّهَا عَلَىَّ، فَقَالَ يَا رَسُولَ اللَّهِ، لَوْ أَسْتَطِيعُ الْجِهَادَ لَجَاهَدْتُ‏.‏ وَكَانَ رَجُلاً أَعْمَى، فَأَنْزَلَ اللَّهُ تَبَارَكَ وَتَعَالَى عَلَى رَسُولِهِ صلى الله عليه وسلم وَفَخِذُهُ عَلَى فَخِذِي، فَثَقُلَتْ عَلَىَّ حَتَّى خِفْتُ أَنْ تَرُضَّ فَخِذِي، ثُمَّ سُرِّيَ عَنْهُ، فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{‏غَيْرُ أُولِي الضَّرَرِ‏}‏‏.‏

Narrated Sahl bin Sa`d As-Sa`idi:I saw Marwan bin Al-Hakam sitting in the Mosque. So I came forward and sat by his side. He told us that Zaid bin Thabit had told him that Allah's Messenger (ﷺ) had dictated to him the Divine Verse: "Not equal are those believers who sit (at home) and those who strive hard and fight in the Cause of Allah with their wealth and lives.' (4.95) Zaid said, "Ibn Um-Maktum came to the Prophet (ﷺ) while he was dictating to me that very Verse. On that Ibn Um Maktum said, "O Allah's Messenger (ﷺ)! If I had power, I would surely take part in Jihad." He was a blind man. So Allah sent down revelation to His Apostle while his thigh was on mine and it became so heavy for me that I feared that my thigh would be broken. Then that state of the Prophet (ﷺ) was over after Allah revealed "...except those who are disabled (by injury or are blind or lame etc)
