1. Murabaha: (Cost-Plus Financing) Sale on profit. Technically a contract of sale in which the seller declares his cost and profit. This has been adopted as a mode of financing by a number of Islamic banks. As a financing technique, it involves a request by the client to the bank to purchase a certain item for him. The bank does that for a definite profit over the cost which is settled in advance. Some people have questioned the legality of this financing technique because of its similarity to riba or interest.
