Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) (a report) with the same meaning as the hadith of Humayd, (except) that it was a group from the tribe of Ukl; after that the Prophet (peace and blessings be upon him) "forbade mutilation."
