It was narrated from Abu Hurairah that someone asked the Messenger of Allahﷺ about praying in a single garment, and he said:

"Does everyone of you have two garments?"

أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ سَائِلاً، سَأَلَ رَسُولَ اللَّهِ ﷺ عَنِ الصَّلاَةِ فِي الثَّوْبِ الْوَاحِدِ فَقَالَ " أَوَلِكُلِّكُمْ ثَوْبَانِ " .
