To take the prizes that stores

Q: I own a shop which sells perfumes, accessories and bags. I want to promote my sales by offering some prizes to the buyers in the following way: if a person buys items for 200 Riyals, they draw a card and win the prize written inside it. If they buy items for 400 Riyals, they take two cards and two prizes, and so on. The prizes vary between expensive ones, which are of low percentage; average-priced ones, which are of medium percentage; and those that their value is 10% of the item's value (i.e. twenty Riyals or more), which are of high percentage. This means that any client must win a prize. However, its price is variable. It can be a recorder, an air conditioner, a television, a lighter or a bottle of perfume. It is all a matter of luck. As for the goods sold on those days, they are sold for the same price as the regular days; there is no increase or decrease in the price. The prizes are restricted only to retail customers, not wholesalers, because the shop deals with some wholesale clients. The workers in the shop (Part No. 15; Page No. 193) or the organizers are not entitled to draw any of these cards when we advertise them in the local newspapers to withdraw the attention of the people. Please answer my question and guide me to the interest of this world and the Hereafter. May Allah protect you.

A: If the case is as you have mentioned, it is Haram (prohibited) to give the buyers prizes this way, because it entails gambling to promote the goods and increase the sales, even if the goods are sold for the same price. It also harms the other sellers, unless they follow the same method, which encourages gambling to promote trade and increase profit. This leads to bearing grudges, kindling the fire of enmity and hatred, and acquiring money undeservedly. Some people might buy goods for 200 Riyals, and they win a recorder, an air conditioner or a television. Others might buy goods for the same value, and they win a lighter or a bottle of perfume which is worth ten or twenty Riyals. (Part No. 15; Page No. 194) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
