The ruling on appointing a bank to buy a car and sell it on the same day

Question:
He says: Honorable Shaykh, may Allah grant you success, is it permissible for a man to appoint a bank to buy a car for him, and then appoint it to sell the car at the same day's price?

Answer:
The bank has no cars, no goods, and no iron. They lie to people, saying, "We have iron, we have cars, we have goods in such-and-such a place," which may be outside the Kingdom, yet they have nothing. Then they say, "Appoint us to sell it." Their intention is only the money. They took the money when it came, under the name of buying and selling, but there is no buying or selling. They hand over money and take an increase on it. This is a lie and riba (usury or interest), and it is not permissible.
Yes, if they have goods, they should display them in their warehouses. If they are truthful, they display the goods in their warehouses, and the buyer takes possession of them. If the buyer buys them from them, he takes them out and sells them outside their premises. But the trader does not fit this.
