Some people say that it is not permissible to trade with paper money.

Answer

To those who say that paper money is haraam, say that you agree. Then ask them to practically implement what they are saying. They should not deal at all in paper money. They should throw away all their paper money. If they refuse to do so, they will be hypocrites. These people are insolently stupid. They do not understand the operation of the principles of the Shariah. We also say that the current paper money is haraam. However, we are trapped in a vicious shaitaani capitalist system from which extrication in the present circumstances is impossible. Those who say that it is haraam, do freely utilize money paper. Currently there is no alternative.
