This summary offers a concise overview of the entire book in less than 30 minutes reading time. However this work does not replace in any case Noah Feldman's book.Feldman reveals how the classical Islamic constitution governed through and was legitimated by law and shows how the balance of powers was destroyed by the incomplete reforms of the modern era.
