Dr. Monzer Kahf, a prominent Muslim economist and counselor, answers: The practice of chain pyramidal commission is permissible provided there is full disclosure, i.e., all TCO’s down the line know the structure of commission and know that the prices they are charged include all these commission up to the top of the pyramid. There is nothing in the Shari`ah that prevents giving commission to solicitors of business, as long as it is known to the person on the other side of the transaction. If there is no full disclosure it may become similar to bribes or at least cheating.
