Reinterpreting Classical Theological Foundations: Modern Approaches to Usul al-Din in Islamic Scholarship

Abstract

Usul al-Din is a theological foundation in Islam that plays an important role in shaping the principles of faith, law, and ethics. Along with social and intellectual change, there is a need to reinterpret this classical theological foundation to be relevant to contemporary challenges. This research aims to explore how modern approaches can be applied in the reinterpretation of Usul al-Din, as well as how the integration of traditional concepts with philosophical and sociological analysis can provide a more holistic understanding of Islamic issues. The method used is library research that examines classical works such as Al-Mustasfa by Al-Ghazali and Mafatih al-Ghayb by Fakhr al-Din al-Razi, as well as journal articles that discuss the evolution of Islamic theology. The results of the study show that a multidisciplinary approach that combines Usul al-Fiqh, Islamic philosophy, and social sciences is able to enrich the understanding of Usul al-Din in facing the challenges of globalization, pluralism, and social injustice. This integration also allows Usul al-Din to function as a theological and ethical instrument in solving modern humanitarian problems. The reinterpretation carried out contributes to shaping an Islamic narrative that is inclusive, progressive, and adaptive to changing times.
