Sahih Bukhari
Bathing (Ghusl)
Volume: 001 / Book Number: 005 / Hadith Number: 249
Narrated Maimuna:
(the wife of the Prophet) Allah's Apostle performed ablution like that for the prayer but did not wash his feet. He washed off the discharge from his private parts and then poured water over his body. He withdrew his feet from that place (the place where he took the bath) and then washed them. And that was his way of taking the bath of Janaba.
