(4) باب مَنْ أَفَاضَ عَلَى رَأْسِهِ ثَلاَثًا
Narrated Abu Ja`far:
Jabir bin `Abdullah said to me, "Your cousin (Hasan bin Muhammad bin Al-Hanafiya) came to me and asked about the bath of Janaba. I replied, 'The Prophet (ﷺ) uses to take three handfuls of water, pour them on his head and then pour more water over his body.' Al-Hasan said to me, 'I am a hairy man.' I replied, 'The Prophet (ﷺ) had more hair than you'. "
