question #3 Sahih Muslim 366d, Book 3, Hadith 136 : What guidance does Islam provide regarding the use of products from non-Muslim regions?

I asked ‘Abdullah b. ‘Abbas saying: We are the inhabitants of the western regions. The Magians come to us with skins full of water and fat. He said: Drink. I said to him: Is it your own opinion? Ibn Abbas said: I heard the Messenger of Allah (ﷺ) say: Tanning purifies it (the skin).
