Is it permissible to purchase a car through a Murabaha transaction from an Islamic bank, given that there is a purchase contract between the bank and the company that includes a "khiyar" (option) clause for the buyer (the bank), and the car is delivered to the customer before the bank fully pays its value to the company, and then the customer pays the car's insurance to the company?

For a Murabaha sale to the one who commands the purchase to be valid, the bank must own the commodity before selling it to the client. Otherwise, the sale is void, based on the saying of the Prophet, peace and blessings be upon him: "Do not sell what you do not possess." As for selling the commodity during the buyer's option period alone, it is permissible, and his disposition is effective, and his option is annulled. Accordingly, the bank's sale of the car to the client during the buyer's option period is permissible. It should be noted that commercial insurance is not permissible.
