Is the hide of an animal slaughtered for other than Allah purified by tanning?

The hide of an animal that died naturally and was not slaughtered Islamically, or was slaughtered in the name of other than Allah, becomes purified through tanning. Tanning purifies the hides of naturally dead animals in general, without differentiation between what was slaughtered in the name of other than Allah and what died without proper slaughter (dhakah). The Messenger of Allah, peace and blessings be upon him, said concerning a dead sheep: "Why did you not take its hide, tan it, and benefit from it?" They said: "It is carrion." He replied: "Only its eating is forbidden."
