The Indonesian Journal of Islamic Law (IJIL) (P-ISSN: 3089-5839 | E-ISSN: 2615-7543) is a peer-reviewed academic international journal published biannually (June and December) by the Postgraduate Programme of Universitas Islam Negeri (UIN) Kiai Haji Achmad Siddiq Jember, Indonesia, and managed by the Department of Islamic Family Law. Established in 2018, the IJIL is dedicated to publishing original, high-quality research on Islamic law as a discursive and institutional phenomenon, with particular attention to ijtihād, legal reasoning, and perspectives from the Global South. The journal seeks to advance scholarly understanding of how Islamic law is interpreted, institutionalised, contested, and reformed within social, political, and legal institutions—especially in Southeast Asia and other Global South contexts—while contributing to international debates on Islamic law, legal pluralism, and legal change.

The journal publishes only original research articles that demonstrate methodological rigour and make a clear theoretical, empirical, or scholarly contribution to Islamic law scholarship. It welcomes welcomes contributions from scholars and practitioners employing socio-legal, qualitative, comparative, and interdisciplinary approaches to the study of Islamic law. Its scope includes, but is not limited to, the following areas: Islamic Law and Socio-Legal Transformation; Judicial Institutions, Governance, and Legal Authority; Family Law, Gender, and Social Justice; Islamic Legal Thought, Uṣūl al-Fiqh, and Maqāṣid al-Sharīʿah; Global South, Postcolonial, and Decolonial Approaches to Islamic Law; Digital Society, Technology, and Contemporary Fatwa Practices; and Islamic Law, Public Ethics, and Economic Governance.

Since its inception in 2018, IJIL has published original research by scholars from more than 45 countries across five continents, namely Asia, Africa, the Americas, Europe, and Australia, contributing to international scholarly debates on Islamic law, legal pluralism, and legal change across diverse jurisdictions and Global South contexts.
