Malik said: As for when a man sells a commodity to another man and finalizes its sale, then the buyer regrets it and says to the seller: "Reduce (the price) for me," but the seller refuses and says: "Sell, and there is no reduction for you," then there is no harm in this, because it is not of risk, but rather it is something he has granted him, and their sale contract was not based on that, and this is the practice among us.
