Islamic banking is not a totally new concept in the world. However, there is still a dearth of basic as well advance level literature on different aspects of Islamic banking. This monograph is based on extensive literature review, discussions with eminent scholars and discussion forums on different aspects of Islamic banking. We have tried to cover each related topic in easy an understanding way, so that most of readers can benefit from it. A general concept is added for conventional banking, and detailed concepts and practical implications of Islamic banking are included. We have used terms Islamic banking, shariyya banking, Islamic bank and shariya bank simultaneously, with an operational definition of "a banking system operating on the principles of Islamic economy and teachings."
