It was narrated that 'Abdullah bin Mughaffal said: "The Messenger of Allah (ﷺ) commanded that dogs be killed. He said: “What do they have to do with dogs?' And he granted a concession regarding hunting dogs and sheepdogs. And he said: “If a dog licks a vessel, wash it seven times, and rub it the eighth time with dust.' Abu Hurairah differed from him and said: “Rub it one time with dust”””"
