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.

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.

Narrated Rafi bin Khadij: that he said, "O Allah's Apostle! We have no knife." The Prophet said, "if the killing tool causes blood to gush out, and if Allah's Name is mentioned, eat (of the slaughtered animal). But do not slaughter with a nail or a tooth, for the nail is the knife of Ethiopians and a tooth is a bone." Suddenly a camel ran away and it was stopped (with an arrow). The Prophet then said, "Of these camels there are some which are as wild as wild beasts; so if one of them runs away from you and you cannot catch it, treat it in this manner (i.e. shoot it with an arrow).
