What was narrated by Muhammad ibn Ya‘qub, from Muhammad ibn Yahya, from Muhammad ibn al-Husayn, from Uthman ibn ‘Isa, from Sama‘ah, who said: I asked Him عليه السلام about a man who wraps himself in a single garment during prayer. Imam عليه السلام said: "He should not wrap himself in a single garment completely. But if he wraps it across himself (tawashshaha) and covers his shoulders, then there is no problem."
