Abu Huraira said, "When the Prophet went to the privy I brought him water in a small vessel or a skin and he cleaned himself, after which he wiped his hand on the ground. I then brought him another vessel and he performed ablution.” Abu Dawud transmitted it, and Darimi and Nasa’i transmitted something similar.
