Cats

CATS. Arabic Hirrah. According to a Hadis of Abu Qutadah, who was one of the Companions, Muhammad said, “Cats are not impure, they keep watch around us.” He used water from which a cat had drunk for his purifications and his wife `Ayishah ate from a vessel from which a cat had eaten. (Mishkat, book iii., c. 10, pt. 2.)
