Sunan Abi Dawud Book 2, Hadith 241
‘A’ishah said; the prophet (ﷺ) prayed in a single (piece of) cloth whose one part was upon me.
I saw the people tying their wrappers over their necks like children due to the narrowness of the wrappers behind the Messenger of Allah (May peace be upon him) during prayer. Someone said: Body of women, do not raise your heads until the men raise (their heads).
I said: Messenger of Allah, I am a man who goes out hunting; may I pray in a single shirt? He replied: Yes, but fasten it even if it should be with a thorn.
