Islamic affairs institutions play an important role in the development of Islam and the Muslim community in a country like Malaysia that has a large Muslim population. They provide a variety of services to the Muslim community, including education, financial aid, and social assistance. However, Islamic affairs institutions are often considered incompetent in managing Islamic affairs thus affecting the confidence of Muslims. Consequently, these institutions must be evaluated to identify areas of improvement and enhance their performance. Therefore, this study aims to explore pertinent indicators to measure the performance of Islamic affairs institutions in Malaysia. This study also describes performance measurement indicators that include various aspects of Islamic affairs, such as mosque management, Islamic education, and Islamic family management. To achieve the objective of the study, a qualitative approach was used through content analysis as a method to analyse the data. The findings of the study can contribute to identifying key indicators that can be utilised as a tool to evaluate the institution's performance. This study will help policy makers, managers, and researchers in improving the performance of Islamic affairs institutions.
