Urwah bin al-Zubayr (may Allah have mercy on him) said: Cleansing oneself after relieving oneself (istinja) was mentioned in the presence of the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Are three stones in which there is no dung not sufficient for any one of you?" Hisham said: And Abu Wajzah (also) narrated this to me from Umarah bin Khuzaymah bin Thabit. It was said to Sufyan: People call (this narrator) Abu Khuzaymah. He said: No, he is Abu Wajzah the poet.
