I bought a car on installments, then sold it to another person on installments, on the condition that the person demanding the installments from me would agree, and he agreed, then he sold the car in the same session

The questioner : I bought a car on installments, then sold it to another person on installments, on the condition that the person demanding the installments from me would accept, and he agreed. Then he sold the car in the same session to a person he knows, in exchange for a debt that person owed him, and he agreed to that. However, the paperwork for this car was done between me and the other person whom he knows, and the price was not mentioned in the sale document because he did not have the funds for the paperwork, the dealer, and the vehicle registration. Is this sale permissible? And if this falls under riba, what must I do? Guide us, may Allah reward you.

The Shaykh : I direct you, O brother questioner, to go with your opponents to the court.

The questioner : May Allah bless you, O honorable Shaykh.
