Chapter 1: Purification (Kitab Al-Taharah)
‘Urwah reported on the Authority of his father a tradition from ‘Ali b. Abi Talib who said: I Asked al-Miqdad (to consult the prophet). He then narrated the tradition bearing the same meaning. Abu Dawud said; this tradition has been reported with another chain of narrators. This version does not mention the word “testicles”.
