Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: We were washing the Messenger of Allah (peace and blessings be upon him) when a man came and knocked at the door. He said: I adjure you by Allah to give me a share today in (the service of) the Messenger of Allah (peace and blessings be upon him). So Ali (may Allah be pleased with him) said: Let him in, and place him behind the curtain so that he can hand us the water. So we let him in, and he kept handing us the water. Ali (may Allah be pleased with him) said: By Allah, whenever I turned (his (peace and blessings be upon him) body) over, I would feel that someone else was turning it over with me. The narrator said: And I heard (a voice) in the house: Do not take his shirt off him.
