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.
— Sahih Bukhari, Volume 7, Book 67: Hunting, Slaughtering, Hadith #410
