What is the ruling on borrowing from or dealing with the Islamic bank in Syria that buys what the customer needs (such as a house or a car) with a profit margin of 7% multiplied by the number of years (to become 35% over five years)? Is this transaction considered usurious or permissible?

Purchasing goods such as a car or a house through Murabaha to the one who promises to buy, as conducted by Islamic banks, is permissible, provided that one reviews the correct regulations and steps for it. Similarly, investing in or with an Islamic bank is permissible as long as the bank adheres to Sharia compliance in its dealings.
