"Does everyone of you have two garments?"  

أَنَّ سَائِلاً سَأَلَ رَسُولَ اللَّهِ ﷺ عَنِ الصَّلاَةِ فِي الثَّوْبِ الْوَاحِدِ فَقَالَ أَوَلِكُلِّكُمْ ثَوْبَانِ  

It was narrated from Umar bin Abi Salamah that he saw Messenger of Allah ﷺpraying in a single garment in the house of Umm Salamah, putting the ends of it on his shoulders."  

أَنَّهُ رَأَى رَسُولَ اللَّهِ ﷺ يُصَلِّي فِي ثَوْبٍ وَاحِدٍ فِي بَيْتِ أُمِّ سَلَمَةَ وَاضِعًا طَرَفَيْهِ عَلَى عَاتِقَيْهِ
