Abstract

Measurements play a significant role in the scientific investigation of religious phenomena. The study of religion, in general, has attracted considerable attention from academia and literature. The aim of this study was to conduct a systematic analysis of the literature regarding scales that have been developed for measuring variables with Islamic relevance and importance, having a theoretical framework embedded in the primary sources of Islamic literature (the Quran and hadith) and validated on Muslim samples. Six well-known databases were selected—ScienceDirect, Web of Science, Springer, Taylor & Francis, Emerald Insight, and Google Scholar—to conduct an in-depth search of existing literature on the topic. Results revealed three broad concepts that have been the focus of measurement: religiosity, spirituality, and morality. Based on our analysis, it can be suggested that although there has been an increase in measuring Islamic religiousness in recent years, there is scope for improvement. This analytical review can be a valuable resource for researchers interested in selecting a valid and trustworthy scale that meets the criteria of their study settings.
