Narrated by Hisham
Hisham narrated it from his father, who narrated it on the authority of 'Aisha that when the Apostle (may peace be upon him) took a bath because of sexual inter-course, he firstwashed the palms of his hands three times, and then the whole hadith was transmitted like that based on the authority of Abu Mu'awyia, but no mention is made of the washing of feet.
