Purification (Kitab Al-Taharah)

Dawud :: Book 1 : Hadith 219

Narrated AbuRafi':

One day the Prophet (peace_be_upon_him) had intercourse with all his wives. He took a bath after each intercourse. I asked him: Apostle of Allah, why don't you make it a single bath? He replied: This is more purifying, better and cleaning.
