Q: Please advise if the following store credit and voucher operations are permissible: (1) “Earn credit by referring your friends to shop on [online store]. Simply invite friends to sign-up via email and you will earn R100 store credit when each one spends R200 or more for the first time.” (2) “Employees will be paid via vouchers that can be used to purchase commodities from [so-and-so] store. Vouchers cannot be redeemed for cash. It is not possible to use such vouchers at a store other than the one stipulated.”

And Allah Ta’ala (الله تعالى) knows best.
