Ka‘b ibn Mālik (may Allah be pleased with him) reported: A woman slaughtered a sheep with a sharp stone. The Prophet (may Allah's peace and blessings be upon him) was asked about it and he ordered that it be eaten.
Explanation
In this Hadīth, Ka‘b ibn Mālik (may Allah be pleased with him) tells that a woman slaughtered a sheep with a stone. This woman was grazing some sheep near Mount Uhud and a wolf attacked one of her sheep without killing it. She chased the wolf away, took a sharp stone and slaughtered the sheep with it. The Prophet (may Allah's peace and blessings be upon him) was then asked about what she had done, and he permitted eating that sheep.
