The Ruling on a Real Estate Broker Increasing the Seller's Price

Question:
This questioner owns a property. He says: I am offering my property for sale, and we ask the owner, for example, "How much are you selling this property for?" He mentions, for example, one million riyals. We then say to him, "If we add one hundred thousand riyals, or take one hundred riyals above the million, is that for us?" He says, "Anything above the million is yours." Then we sell it in the market and take the extra, while the buyer does not know. Is this method correct?

Answer:
If you informed him of the reality, because you sold it, and so on, and he had specified a limit for you, and you sold it for more than what he specified for you, and you informed him of that, and he allowed you the increase, then there is no harm in that; because the right belongs to him, so if he permits it, there is no harm. Otherwise, you are entitled to the amount that is customary for the effort, which they call the effort and the brokerage.
