What is the ruling on buying a car from a car showroom and selling the car to the showroom owner without even using it, noting that the person who sold it first bought the car from the same showroom?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

First of all, it is permissible to make an installment sale, namely to sell an object at a deferred price, whether the deferred price will be paid in full or in installments. If you buy a car, then it is not permissible that you sell it unless you have received it and it has become in your full possession, even if you do not move it from its place. If you do so, then it is permissible for you to sell the car. However, to sell the car to the showroom that sold it to the person from whom you bought the car is a forbidden trick called ‘Eenah sale, if the showroom gives the car to the buyer on the condition that the buyer will sell the car to a person who will sell the car to the same showroom.

However, if the showroom sells the car which is then received by the buyer, and the buyer sells it to you and thus you have received and possessed it, then you offer the car for sale and the showroom buys it from you, without predetermined agreement, then this is permissible.

Allaah Knows best.
