[Machine] When the verse "Not equal are those believers remaining [at home] - other than the disabled" [Quran 4:95] was revealed, the Messenger of Allah ﷺ instructed Zaid to write it. Then, Ibn Umm Maktum came and complained about his disability to the Messenger of Allah ﷺ. So, Allah ﷻ revealed the verse "Except for the disabled" [Quran 4:95].
لَمَّا نَزَلَتْ لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ وَالْمُجَاهِدُونَ فِي سَبِيلِ اللهِ الْآيَةَ أَمَرَ رَسُولُ اللهِ ﷺ زَيْدًا فَكَتَبَهَا فَجَاءَ ابْنُ أُمِّ مَكْتُومٍ فَشَكَا ضَرَارَتَهُ إِلَى رَسُولِ اللهِ ﷺ فَأَنْزَلَ اللهُ ﷻ {غَيْرُ أُولِي الضَّرَرِ} [النساء 95]
