This book provides an in-depth picture of how Islamic finance, which began as a commercial practice half a century ago, has grown globally through the trials and errors of bankers and scholars, with analyses of various controversies (idea vs. reality, interest vs. profit etc.) within the financial industry and academia (Islamic economics) and its entanglement with the capitalism that Islamic finance has confronted. Furthermore, the post-capitalist potential of the Islamic economy will be discussed from the history and dynamism of the practice of Islamic finance.
