This multidisciplinary book on Islamic finance covers Islamic economic, financial, and legal systems, insurance (takaful), commercial jurisprudence, and the socio-political and political-economy of the Islamic world. It examines the dichotomies and similarities between Islamic and conventional financial systems and suggests future roles and governance of Islamic financial institutions. Distinctive features of the second edition include an emphasis on the theoretical foundations of Islamic finance, the distinctions between the micro- and macroeconomic concepts and theories to the readers, and an expansion on Islamic approved forms of trade dealings, transactions, and contracts. Furthermore, this work discusses the newly introduced Islamic capital market products of the years 2020 to 2022—including the transition from the inter-bank-offer-rates (IBORs) as global benchmark lending rate to the new risk-free-rates (RFRs) that became effective on January 1, 2022—and discusses the transition of Saudi Arabia Monetary Agency to Saudi Central Bank in 2020. Though every effort is made to avoid tedious mathematical proof and derivatives, this work provides working calculations for the pricing of Islamic instruments and provides supplemental materials in the form of faculty resources and students’ study guide and workbook. This work acts as a useful textbook for graduate and advanced undergraduate students who are looking at broadening their knowledge in finance. Similarly, this book is a helpful guide and tool for financial practitioners who are interested in learning more about the innovative discipline of Islamic finance. For financial practitioners to drive maximum benefits from this innovative financing mechanism, they need to know, understand, and participate in the investment opportunities which are provided by Islamic finance.
