Ritual Impurity, the Skins of Predatory Animals, and Tanning

Question:
Honorable Shaykh, may Allah grant you success, he says: You mentioned (may Allah preserve you) that impurity is never purified. Is it if

Answer:
impurity? Yes, indeed. The impurity of the eye is intrinsic impurity that washing does not purify, such as the dog. The impurity of a dog is intrinsic, and the skin of a dog, even if you tan it with tanning agents, does not become pure because it is intrinsically impure. The skins of predators, such as the leopard and the lion, are forbidden to use and to take because they are intrinsically impure. It is forbidden to spread them out, because they are intrinsically impure, and tanning does not purify them. Yes.
