The Ruling on Agencies in Buying and Selling

Question:
Please give us a ruling, may Allah have mercy on you, regarding the ruling on agencies, such as when a person takes an agency for cars or other things, may Allah preserve you?

Answer:
Is there any harm in an agency if one is entrusted with cars, or entrusted with the first cars, provided he is trustworthy, fulfills his duty, and fulfills the trust, and it is for a known fee, a known fee for the car agency, where the car has a fee of one hundred, the car has a fee of two hundred riyals, the bag has such a fee, the house has such a fee, whatever it is, so the agent is given a known fee, or a known shared profit, for example one percent, two percent, five percent for his effort, it is something known, or a known fee, so there is no harm in it, meaning that the agent engages in brokerage, buying, and selling for a known fee, or a known shared portion of half a tenth, meaning one percent, five percent, or one percent, or two percent, or something similar to them, it is clear, a shared portion of the price, or a known estimated amount, every car you sell for him has a fee of one hundred riyals, for you it is one hundred and fifty riyals, for you it is two hundred, and so on, so he must be truthful, and he must be trustworthy, and he must sell as his principals have specified for him, and if they entrusted him and gave him free rein to sell as he sees fit, let him fear Allah, and not harm them, but sell according to the market, or wait until he is satisfied, until he sells with insight, he does not favor this one, and he does not favor that one, but he fears Allah, and advises his principal to what he specifies.
