Imam Bukhari narrates: Ubaidullah bin Musa narrated hadith to us, he said: Hisham bin Urwah narrated hadith to us, from his own father, from Hazrat Umar bin Abi Salamah, may Allah be pleased with him, that the Prophet ﷺ prayed wearing a single cloth, he kept its two ends opposite (he put the right end upon the left shoulder and put the left end upon the right shoulder and tied a knot between them).
