Shariah contains the principles and foundations upon which financial system from an Islamic perspective is established and acts as guidance and framework on which the direction of the industry is set. This would include the whole processes from product conceptual inception of developing shariah product compliance manual, developing product structure, reviewing the legal documentation, and producing report or opinion on the product application in the market. Islamic finance is expected to offer something new to the market instead of a mere replication and modification of conventional practices in Islamic forms. The paper attempts to survey the approach in developing Islamic finance, including the debate on replication and innovation in a product to the structure as well as the gaps between ideals and practices.
