What is the ruling on buying a car through a bank in installments under the murabahah system?

Question:
Honorable Shaykh, a man says: I bought a car through one of the banks under the system called murabahah. The bank sent me to one of the showrooms to inspect the car, and then the bank bought the car and sold it to me on the condition that I pay the amount in installments to the bank with an increase of eight percent per year. After I took possession of the car, I sold it back to the showroom from which I had bought it, because I needed money. I did not proceed with this action until after I heard a fatwa stating that this matter is permissible. Then some students of knowledge informed me that this matter is not permissible, because it is selling what one does not own. Allah knows best.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. There is no doubt that this contract did not meet the conditions of validity. First, because the bank is a riba bank. A riba bank. One should stay away from riba institutions, so as not to cooperate with them in their forbidden work, which is riba? Second, they did not own the car at the time they contracted with him.
Rather, when they contracted and you finished, they went and bought it for you, and this is a matter that is not permissible. Or you bought it and they paid its price and recorded it on you with an increase, and this is explicit riba and is not permissible. But since the matter has happened and you sold the car, you must repent to Allah and not return to such a thing. Yes.
