What did the Prophet Muhammad (saw) permit Ka`b's slave girl to do when they mentioned to him that a sheep of hers was dying?
 Narrated `Abdullah:                     that Ka`b had a slave girl who used to graze his sheep on a small mountain, called "Sl'a", situated near the market. Once a sheep was dying, so she broke a stone and slaughtered it with it. When they mentioned that to the Prophet, he, permitted them to eat it.
