Ar-Rubaiyi‘ daughter of Mu'awwidh said that she saw the Prophet performing ablution, saying that he wiped his head front and back, his temples and his ears once. A version says that he performed ablution and inserted his two fingers in his ear-holes.
Abu Dawud transmitted it. Tirmidhi transmitted the first version, and Ahmad and Ibn Majah the second.
We were sitting looking at ‘Ali when he performed ablution. He inserted his right hand, filled his mouth, rinsed it, snuffed up water and ejected the mucus with the left hand, doing this three times, then said, "If anyone is pleased to look at God's messenger’s method of performing ablution, this is how he did it.”
