The ruling on earning money from working in a cafe that serves shisha

Question:
May Allah reward you. This questioner, Khalifa, says: A friend of mine owns a cafe for drinking tea and coffee, and it serves shisha. What is the ruling on the money that comes in from this cafe?

Answer:
This contains both lawful and forbidden elements. The price of the forbidden items is forbidden, and the price of the shisha, tobacco, and these intoxicants is forbidden. As for selling tea and other permissible items, their price is lawful. So this is mixed money, containing both lawful and forbidden. Yes.
