What is the ruling on selling goods in the place where they were purchased?

The questioner : Your Eminence, may Allah forgive you, a person comes to one of the exhibitions and buys a car, then says to the owner of the exhibition: "Sell it if it brings a profit of such-and-such," without moving it from its place to his home or moving it at all. Is this permissible?

The Shaykh : This is prohibited, because the Prophet (peace and blessings be upon him) said: . So if he takes it to another place and says to the owner of the exhibition: "Sell it," there is no harm. He may sell it while it is in its place, but he must not sell it in the same exhibition.
