Sale of goods with an agreed upon profit mark up on the cost. Murabaha sale is of two types. In the first type, the Islamic bank purchases the goods and makes them available for sale without any prior promise from a customer to purchase them. In the second type, the Islamic bank purchases the goods ordered by a customer from a third party and then sells these goods to the same customer. In the latter case, the Islamic bank purchases the goods only after a customer has made a promise to purchase them from the bank.
