Is it permissible for a commercial brokerage firm that does not possess the necessary capital to conclude deals to seek assistance from relatives to finance the purchase of goods, and then share the profits with them, given that the client is aware of the total price of the deal and is ready to open a bank credit? And is it permissible to buy and market what is known as "sailors' fish," which the sailors claim the ship's captain gave them?

Brokerage is permissible, and there is no objection to taking a specific and known commission from clients in return for mediating for them. It is also permissible to take a commission from cousins in return for mediating in the completion of a deal through them. There is no harm in the broker taking a commission from both parties or one of them, according to custom or agreement. Scholars have differed regarding the permissibility of the commission being a percentage of the profit. The majority of jurists stipulate that the commission must be known, and they believe that it being a percentage of the profit leads to its uncertainty. However, some scholars permit the brokerage fee to be a percentage of the profit, and this is an opinion that holds considerable weight.
