Imam Bukhari narrates: Muhammad bin Al-Muthanna narrated hadith to us, he said: Yahya narrated hadith to us, he said: Hisham narrated hadith to us, he said: My father narrated hadith to me, from Hazrat Umar bin Abi Salamah, may Allah be pleased with him,

that he saw the Prophet ﷺ, he was praying wearing a single cloth in the house of Hazrat Umm Salamah, may Allah be pleased with her, and he had kept the two opposite ends of that cloth upon his shoulders (he put the right end upon the left shoulder and put the left end upon the right shoulder, then tied a knot between them).
