Zulfiqar Ali Shah’s book is an extensive undertaking that is encyclopedic in its scope and ambitious in its aims. Although written with a view to demonstrating the relative superiority of the Qur’anic and Muslim understanding of the transcendent God, the book’s lengthy treatments of corresponding biblical, Jewish, and Christian understandings seem largely fair, balanced and thorough. Scholars dealing with concepts of God in the three traditions will have to come to terms with this work in the future.
