The ruling on benefiting from points earned with every purchase

Question:
He says: Honorable Shaykh, may Allah grant you success. Some stores issue cards, and with every purchase the buyer earns points. Once he reaches a certain number of points, he receives prizes or gets a discount in prices, for example twenty percent. Is this permissible?

Answer:
No, this is also gambling, and it is not permissible. Fatwas have been issued by the Committee prohibiting it due to its harms. First, it harms other stores that do not do this, and people turn to the one who offers these things. Second, you do not see them giving you anything from their money; rather, they increase the price and take from your money, saying, "We gave you a prize," but they are taking it from you. They are deceivers; this is deception in consuming people's wealth without right. This is absolutely not permissible. Buying and selling must be kept free from these matters and these nonsense things. Yes.
