It is narrated from Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When one of you relieves himself, let him clean himself with three stones, for indeed that is sufficient for him."
No one narrated this hadith from al-Awza'i (may Allah have mercy on him) as a marfu' (Prophetic) narration except al-Hiql (may Allah have mercy on him), and Amr (may Allah have mercy on him) is alone in narrating it from al-Hiql.
