When the Qur'anic verse:" Those who sit (at home) from among mu'min" (iv. 94) was revealed, the son of Umm Maktum spoke to him (the Holy Prophet). (At this). the words:" other than those who have a trouble (illness)" were revealed.
وَحَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا ابْنُ بِشْرٍ، عَنْ مِسْعَرٍ، حَدَّثَنِي أَبُو إِسْحَاقَ، عَنِ الْبَرَاءِ، قَالَ لَمَّا نَزَلَتْ لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ كَلَّمَهُ ابْنُ أُمِّ مَكْتُومٍ فَنَزَلَتْ غَيْرُ أُولِي الضَّرَرِ
