It is narrated from Sayyiduna Ka'b bin Malik (may Allah be pleased with him) that he had some goats that used to graze on Mount Sal', and one of them fell. A slave girl went down and slaughtered it. Ka'b (may Allah be pleased with him) asked the Messenger of Allah (peace and blessings be upon him) about it, and he (peace and blessings be upon him) saw no harm in it.
