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 (ﷺ) and ask him, or, till I send someone to ask him." So he went to the Prophet (ﷺ) or sent someone to him The Prophet (ﷺ) permitted (them) to eat it
