Islamic banking refers to a system of banking or banking activity that is consistent with the principles of Islamic law (Sharia) and its practical application through the development of Islamic economics. Sharia prohibits the payment of fees for the renting of money (Riba) for specific terms, as well as investing in businesses that provide goods or services considered contrary to its principles (Haraam). While these principles were used as the basis for a flourishing economy in earlier times, it is only in the late 20th century that a number of Islamic banks were formed to apply these principles to private or semi-private commercial institutions within the Muslim community.
