Rules of Brokerage when Selling something
Issue No.1821- If a person gives a commodity to another person and fixes its price and says: "If you sell this commodity at a price higher than that the sale proceeds in excess of that will be your property" , the transaction is in order, and the extra amount is that of the broker. Similarly, if he says, “I sell this commodity to you at this price” and he says, “I have accepted” and then, if he sells it more than that price, the extra amount thus will be his.
