Correct Answer: B) The literal translation of the word "riba" is "increase" or "excess" , which is forbidden under the Syariah law. Islamic banking is governed under the Syariah law. Hence any accrued interest for deposit and/or loan that is predetermined, which is considered as an "increase" or "excess" , is prohibited. Nevertheless, any profit from business activity that involves a certain risk where the profit cannot be determined is allowed since it depends on the relative success of the businesses or entrepreneurial activities. The element of sharing the undeterminable profit is allowed and does not contravene the Islamic principles and is acceptable in Islamic banking.
