And ‘Ubaydullah ibn Mu‘ādh narrated to us: my father narrated to us: Shu‘bah narrated to us, from Abū al-Tayyāḥ, who heard Muṭarrif ibn ‘Abdillāh narrating from Ibn al-Mughaffal, who said: The Messenger of Allah (peace and blessings be upon him) ordered the killing of dogs. Then he said: "What is the matter with them and with dogs?" Then he granted a concession regarding the hunting dog and the sheepdog, and said: "When a dog drinks from a vessel, wash it seven times, and rub it the eighth time with dust."
