The book is structured in five parts. Part 1 (Chapters 1–5) presents a theoretical framework of Islamic economics, discusses the relationship between religion and economics, and explains the Islamic worldview. It examines the definition, characteristics, scope, objectives, and methodology of Islamic economics and presents approaches to and processes of theory building in Islamic economics. Moreover, the book reports that the topic of Chapter 3, “Theory Building in Islamic Economics,” may not be covered in other elementary textbooks. Furthermore, the section presents ethics in Islamic economics while emphasizing the importance of other systems; the authors note that “[a]ny system that embeds ethical humanitarian values and philosophies and environment-conscious practices will positively impact societies and sustainable growth” (p. 102).
