Development of Islamic Law in Indonesia

Abstract

The development of Islamic law in Indonesia represents a historical, sociological, and juridical phenomenon that reflects the ongoing interaction between religious norms, customary practices, and the state legal system. Islamic law functions not only as a set of religious norms but also as a moral and philosophical foundation that shapes Indonesia’s social and legal structures. Since the arrival of Islam in the Indonesian archipelago in the 13th century, Islamic law has become an integral part of local society, particularly in family, inheritance, waqf, and commercial matters. Its influence expanded during the era of Islamic kingdoms, where Islamic law served as the foundation of governance and judicial systems, notably in the Sultanates of Aceh, Demak, and Ternate. During the Dutch colonial era, the position of Islamic law faced suppression under the receptie theory, which limited its validity to cases where it was accepted by customary law. This policy subordinated Islamic law to colonial and customary legal systems. Nevertheless, Muslim scholars and jurists persistently defended the relevance of Islamic law within Indonesia’s legal system. After independence, a new perspective known as receptio a contrario emerged, challenging colonial interpretations and affirming that customary law was valid only insofar as it did not contradict Islamic principles. Subsequent efforts focused on integrating Islamic law into the national legal system based on justice, humanity, and social welfare. The enactment of the Compilation of Islamic Law (KHI) in 1991 marked a significant milestone in codifying Islamic law for Indonesian Muslims. Moreover, institutions such as the Supreme Court, the Sharia Courts, and the Ministry of Religious Affairs have strengthened the implementation of Islamic legal principles within the state framework. Contemporary Islamic legal development in Indonesia also includes modern innovations such as fatwas issued by the Indonesian Ulema Council (MUI), Islamic banking regulations, and family law reforms grounded in the principles of maqāṣid al-sharī‘ah. In the modern era, the expansion of Islamic law encompasses broader areas, including finance, environmental law, and public governance. These developments reflect the adaptability and dynamic nature of Islamic law in responding to societal changes. However, challenges remain in harmonizing Sharia principles with Indonesia’s pluralistic legal structure. Therefore, the development of Islamic law must proceed through gradual, systematic, and dialogical processes that uphold justice, public welfare, and the supremacy of law. This study employs a normative-historical and sociological approach with descriptive analysis based on literature, legislation, and scholarly research. The findings reveal that Islamic law in Indonesia is a living and evolving legal system that continuously adapts to social transformations while maintaining its foundational principles of justice and maslahah (public interest). Ultimately, Islamic law contributes significantly to the creation of a national legal system rooted in religious and moral values while reflecting the unique identity of the Indonesian nation
