Institutions and their subsequent institutional reality are considered as a framework for many social behaviors and their understanding provides the grounds for the recognition of social behaviors and the prediction of their formation. Economic activities and events in each society are formed on the basis of its institutional structure as such the neoclassical scientific theories arising from the construction of particular institutions cannot be considered appropriate for another society with a different institutional structure.

Islamic law affects human behavior and brings some economic and social consequences since the religious law are considered as social rational entities that form both real entities and other social entities of their own type and can be regarded as institutional realities. When human beings’ social-economic activities are carried out within the framework of Islamic institutions, social interests are indivisible from individual interests. With understanding this necessity with the aim of explaining the methodology of Islamic economics, the author developed the present book with an approach to its institutional reality.
