Brokerage and its fee, and selling to the resident on behalf of the newcomer

Question:
Regarding the broker: if you want him to look for something and you appoint him as your agent, and the merchants agree to what we have established, then we make use of him in that.

Answer:
If you request that he sell the goods, there is no harm in that. You also give him the brokerage fee, which is the wage for his work, and there is no harm in that. However, if he comes forward to you and offers to sell you the goods, this is forbidden. The Messenger of Allah (peace and blessings be upon him) prohibited it: a resident must not sell on behalf of a newcomer. As for the resident in the city, the merchants who have a presence in the city, what do you think of a person coming to them and saying, "I will sell you the land," "I will sell you such and such," or "I will sell you the cars"? The prohibition is specifically regarding the newcomer, meaning the one who has just arrived in the city, only.
