The command of Allah Almighty is: "Say! I do not find in what has been revealed to me anything forbidden to an eater that he eats." Explaining this in detail, Sayyiduna Ibn Abbas (may Allah be pleased with them both) says: Here, "ta'im" (eater) refers to the person who eats. As for teeth, horns, bones, wool, hair, and fur, there is no harm in them, because they are washed. The narrator named Shababa has reported this: "That part of a dead animal is forbidden which is eaten, and that is the flesh. As for the skin, bone, teeth, hair, and wool, it is permissible to use them (for other purposes)." The narrator of this narration, Abu Bakr Hadhli, is weak.
