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." (Using translation from Nasāʾī 764)  

أَنَّهُ رَأَى رَسُولَ اللهِ ﷺ «يُصَلِّي فِي ثَوْبٍ وَاحِدٍ فِي بَيْتِ أُمِّ سَلَمَةَ وَاضِعًا طَرَفَيْهِ عَلَى عَاتِقَيْهِ»
