Despite the obvious link between spirituality, religiosity and ethical judgment, a definition for the nature of this relationship remains elusive due to conceptual and methodological limitations. To address these, we propose an integrative Spiritual-based model derived from categories presumed to be universal across religions and cultural contexts, to guide future business ethics research on religiosity. This article aims to empirically test in the context of Islam. It examines how different Muslims' views of God influence their ethical judgments in organizations, and (...) how this process is mediated by their religious practice and knowledge. Comprising focus group and vignette designs, the study was carried out with a random sample of 427 executives and management professionals from Saudi. After data collection, the study hypotheses were tested using structural equation modeling. The findings confirmed that a view of God based on hope might be more closely associated with unethical judgments than a view based on fear or one balancing hope and fear. Furthermore, religious practice and knowledge were found to mediate the relationship between Muslims' different views of God and their ethical judgments. These results provide unique theoretical insights into religiosity's influence on ethical judgment, with important implications for management. (shrink)
