It was narrated that Sahl bin Sa'd said:

"I saw Marwan bin Al-Hakam sitting and I came and sat with him. He told us that Zaid bin Thabit told him, that the following was revealed to Messenger of Allah ﷺ: (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 when 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.' Then Allah, the Mighty and Sublime, revealed to him - while his thigh was against mine, and became so heavy that I thought my thigh would break, until (the revelation) stopped -: 'Except those who are disabled (by injury or are blind or lame).'" [1]
Abu 'Abdur-Rahman (An-Nasa'i) said: This 'Abdur-Rahman bin Ishaq is tolerable, while 'Abdur-Rahman bin IShaq, from whom reports 'Ali bin Mushir, abu Mu'awiyah, and 'Abdul-Wahid bin Ziyad from An-Nu'man bin Sa'd - he is not trustworthy.

[1] An-Nisa' 4:95.

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ بَزِيعٍ، قَالَ حَدَّثَنَا بِشْرٌ، - يَعْنِي ابْنَ الْمُفَضَّلِ - قَالَ أَنْبَأَنَا عَبْدُ الرَّحْمَنِ بْنُ إِسْحَاقَ، عَنِ الزُّهْرِيِّ، عَنْ سَهْلِ بْنِ سَعْدٍ، قَالَ رَأَيْتُ مَرْوَانَ بْنَ الْحَكَمِ جَالِسًا فَجِئْتُ حَتَّى جَلَسْتُ إِلَيْهِ فَحَدَّثَنَا أَنَّ زَيْدَ بْنَ ثَابِتٍ حَدَّثَهُ أَنَّ رَسُولَ اللَّهِ ﷺ أُنْزِلَ عَلَيْهِ لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ وَالْمُجَاهِدُونَ فِي سَبِيلِ اللَّهِ . فَجَاءَ ابْنُ أُمِّ مَكْتُومٍ وَهُوَ يُمِلُّهَا عَلَىَّ فَقَالَ يَا رَسُولَ اللَّهِ لَوْ أَسْتَطِيعُ الْجِهَادَ لَجَاهَدْتُ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ وَفَخِذُهُ عَلَى فَخِذِي فَثَقُلَتْ عَلَىَّ حَتَّى ظَنَنْتُ أَنْ سَتُرَضُّ فَخِذِي ثُمَّ سُرِّيَ عَنْهُ { غَيْرُ أُولِي الضَّرَرِ } قَالَ أَبُو عَبْدِ الرَّحْمَنِ عَبْدُ الرَّحْمَنِ بْنُ إِسْحَاقَ هَذَا لَيْسَ بِهِ بَأْسٌ وَعَبْدُ الرَّحْمَنِ بْنُ إِسْحَاقَ يَرْوِي عَنْهُ عَلِيُّ بْنُ مُسْهِرٍ وَأَبُو مُعَاوِيَةَ وَعَبْدُ الْوَاحِدِ بْنُ زِيَادٍ عَنِ النُّعْمَانِ بْنِ سَعْدٍ لَيْسَ بِثِقَةٍ .
