سنن أبي داود

'Aishah reported : When the Messenger of Allah (May peace be upon him) would take a bath because of sexual defilement, according to the version of Sulaiman, in the beginning he would pour water with his right hand (upon his left hand); and according to the version of Musaddad, he would wash both (hands) pouring water from the vessel upon his right hand. According to the agreed version, he then would wash the private part. He would then perform ablution as he did for prayer, then put his hands in the vessel and made the water go through his hair. When he knew that water had reached the entire surface of the body and cleaned it well, he would pour water upon his head three times. If some water was left, he would pour it also upon himself.
