Sahih al-Bukhari, 249

Rapporté par Maimuna : (l’épouse du Prophète) Le Messager d’Allah (ﷺ) a fait les ablutions comme pour la prière mais n’a pas lavé ses pieds. Il a lavé les traces sur ses parties intimes puis a versé de l’eau sur son corps. Il a ensuite déplacé ses pieds de cet endroit (où il a pris son bain) et les a lavés. C’était sa façon de faire le bain de Janaba

Narrated Maimuna:(the wife of the Prophet) Allah's Messenger (ﷺ) 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
