Book excerpt: This ground-breaking volume on political Islam takes the question of Islam and secularism in an entirely different direction. It shows how leading Islamists use Islamic legal theory to liberate the political sphere from the narrow exegetical worldviews of classical jurists and modern fundamentalists. Exploring the work of a vanguard of Islamists, the book brilliantly parses out the broadlines of these Islamists’ liberal theory and its underpinning legal grounds. This theory promises much. Beyond resolving the problem of political legitimacy in Muslim majority countries, it opens immense potential for reasonable ‘overlapping consensuses’ between traditional worldviews and modern secular perspectives. Most strikingly, this resolution rests not on a break with the Islamic legal heritage but on rediscovering and refining the most profound aspects of it. The secret of this liberal theory lies in the broad application of the medieval concept of maqasid, the Lawgiver’s aims. This approach shifts the focus from textual analysis emphasizing what God said to a systematic rational exploration of what He intended.
