The book presents a concise but wide-ranging overview of the principal tenets of Twelver-Shia Islam. The author brings together in a single volume many of the themes which are rooted in the classical Shia tradition of scholarship. The book is divided into three chapters, the first dealing with universal themes, the second with theology in the specific sense, and the third with a number of religious questions, practical ruling and contemporary issues.

Adopted from the translator's foreword of the book.
