Is dealing considered usurious if the bank sells building materials in annual installments with a profit margin higher than the market price?

As long as the bank owns the materials and sells them to the customer at a specified price, there is no objection, even if the price is higher than the market price; because deferment has a share in the price. The Islamic Fiqh Academy’s resolution states: "It is permissible to increase the deferred price over the spot price." This is a permissible sales transaction, and Allah has made profit lawful in trade.
