Sunan Abi Dawud Book 2, Hadith 238
I saw the Messenger of Allah (ﷺ) praying girded with a single (piece of) cloth, place its two ends over his shoulders.
if anyone prays in a single piece of cloth, he should cross the two ends.
We came to the Prophet (ﷺ), and a man came and said: Prophet of Allah, what do you say if one prays in a single garment? The Messenger of Allah (ﷺ) then took off his wrapper and combined it with his sheet, and put it on them. He got up and the Prophet of Allah (ﷺ) led us in prayer. When he finished the prayer, he said: Does every one of you have two garments?
