Q 3: I took a customer to a factory or store to purchase some goods. Accordingly, the factory owner gave me a commission for bringing this customer. Is this money Halal (Lawful)
(i.e. The commission)?
What if the factory owner increases the price of every item sold to the customer so that I take the difference in price once the customer makes the purchase; is this permissible? If not, what is the lawful commission?
It is permissible if the factory owner or merchant pays you a sum of money in return for every item sold through you. This payment is meant to encourage you to exert more effort in bringing more customers. However, the permissibility is conditional; the amount of money paid to you should not increase the price of the item and should not inflict any harm on (Part No. 13; Page No. 131) others who are selling the same item. The factory owner or merchant should sell the item for the same price as the others. In this case, it is permissible and there is no prohibition.However, if the money you take from the factory owner or the store increases the price the buyer pays for the item, then it is impermissible for you to take it. This is because the buyer is harmed as the price he has to pay is increased.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
