The author says in the introduction of the second edition, “The overall purpose of this book is to acquaint the reader with the historical factors behind the formulation of Islamic law (Fiqh), in order that he or she may better understand how and why the various schools of Islamic law (Madh-habs) came about.

It is hoped that this understanding will in turn, provide a basis for overcoming the petty differences and divisions which occur when present-day followers of different schools of people without definite schools try to work together. Thus, another aim of this book is to provide a theoretical framework for the reunification of the Madhhabs and an ideological basis for Islamic community work free from the divisive effects of Madh-hab factionalism.” The book consists of six chapters: foundation, establishment, building, flowing, consolidation, and stagnation and decline.
