Use stones for animal slaughter if done properly and without causing unnecessary suffering .

This hadith is about the Prophet Muhammad's opinion on the slaughter of animals. It was narrated from Kab bin Malik's son that a woman slaughtered a sheep using a stone, and when this was mentioned to the Prophet Muhammad, he did not find anything wrong with it. This hadith teaches us that it is permissible to use stones for animal slaughter as long as it meets certain conditions such as making sure that all of the blood has been drained from the animal and ensuring that no unnecessary suffering is inflicted upon them. It also shows us how merciful and compassionate the Prophet Muhammad was towards animals, even in situations where some people may have found fault or seen something wrong.
