The Ruling on Discount Cards

Question: It has become widespread in some commercial establishments and private clinics to issue a card that is given to anyone who wishes to subscribe to it, in exchange for an annual financial fee. The holder of the card receives some free medical examinations during the year, as well as some financial discounts on other laboratory tests.
My question is: Is it permissible to issue such cards, or to deal with them? May Allah reward you with good.

Answer: This practice is not permissible because of the ignorance, gambling, and excessive uncertainty involved in it. Therefore, it is obligatory to leave it. And success is from Allah.
