The ruling on purchasing cars from banks that deal in riba (usury or interest)

Question:
I say: Honorable Shaykh, may Allah grant you success, what is the ruling on purchasing a car or property through a valid legal system from banks that deal in riba in their other transactions?

Answer:
If the cars are in the possession of the banks and owned by the banks, there is no harm in purchasing them, because the Prophet (peace and blessings be upon him) used to buy from the Jews, and they dealt in riba. So if the sale is valid and contains nothing [impermissible], even if one of the parties deals in riba, as long as this transaction is free from riba, there is no harm. And if the bank owns the car and it is in its possession, and it sells it to the customer, there is no harm, even if the bank deals in riba.
