This study explores the implementation of Keas’yariahan education at Al Asy’ariah Mandar University (UNASMAN) and its impact on students' moral development and internalization of pluralistic values. As the first university in West Sulawesi, UNASMAN incorporates Keas’yariahan principles into its academic and extracurricular frameworks to strengthen Islamic ethical awareness while promoting social harmony and respect for diversity. Using a qualitative methodology, this research draws on interviews, observations, and document analysis. Data were analyzed through reduction, thematic presentation, and conclusion drawing, with validity reinforced by triangulation. The findings demonstrate that Keas’yariahan education at UNASMAN operates through structured curricular and co-curricular programs designed to nurture both religious commitment and pluralistic attitudes. The university mandates preaching courses across four consecutive semesters and requires participation in Islamic study programs through its Student Boarding School, ensuring sustained engagement with religious teachings. Beyond ritual observance, Keas’yariahan education emphasizes the application of Islamic values – such as justice, trustworthiness, and social responsibility – in daily life. It frames religious awareness holistically, integrating spiritual devotion (habl min Allah), ethical interpersonal relations (habl min al-nas), and environmental consciousness. By intertwining theological instruction with pluralistic pedagogy, UNASMAN cultivates graduates who embody tolerance, moral integrity, and leadership in a multicultural society.
