Is it permissible to give customers cash vouchers redeemable at other partners, with the store paying the value of the voucher to the partners at an agreed-upon percentage, and is it permissible to establish a company to manage this operation?

It is permissible for a shop owner to offer free shopping vouchers to customers when they make a purchase or when their purchases reach a certain limit, provided that the customer does not pay any consideration for them and that the price of the commodity is not increased because of them. These vouchers are considered a permissible gift. There is no objection to the customer benefiting from the voucher in other places if the shop owner pays its value. Likewise, there is no objection to establishing a company to organize this type of business, such as issuing vouchers, organizing participating companies and shops, and the company taking a certain percentage and settling accounts between the shops.
