What did the Prophet Muhammad (peace be upon him) say when Ka'b asked him about the slave girl who broke a stone and slaughtered one of her sheep?
 Narrated Ka`b:                     that a slave girl of theirs used to shepherd some sheep at Si'a (a mountain near Medina). On seeing one of her sheep dying, she broke a stone and slaughtered it. Ka`b said to his family, "Do not eat (of it) till I go to the Prophet and ask him, or, till I send someone to ask him." So he went to the Prophet or sent someone to him The Prophet permitted (them) to eat it.
