Islamic Law and International Law is a comprehensive examination of differences and similarities between the Islamic legal tradition and international law, especially in the context of dispute settlement. Sharia embraces a unique logic and culture of justice—based on nonconfrontational dispute resolution—as taught by the Quran and the Prophet Muhammad. This book explains how the creeds of Islamic dispute resolution shape the Islamic milieu’s views of international law. Is the Islamic legal tradition ab initio incompatible with international law, and how do states of the Islamic milieu view international courts, mediation, and arbitration? Islamic law constitutes an important part of the domestic legal system in many states of the Islamic milieu—Islamic law states—displacing secular law in state governance and affecting these states’ contemporary international dealings. The book analyzes constitutional and sub-constitutional laws in Islamic law states. The answer to the “Islamic law–international law nexus puzzle” lies in the diversity of how secular laws and religious laws fuse in domestic legal systems across the Islamic milieu. These states are not Islamic to the same degree or in the same way. Thus, different international conflict management methods appeal to different states, depending on each one’s domestic legal system. The main claim of the book is that in many instances the Islamic legal tradition points in one direction while Western-based, secularized international law points in another direction. This conflict is partially softened by the reality that the Islamic legal tradition itself has elements fundamentally compatible with modern international law.
