In this article, we examined the relationship between abusive supervision and deviant workplace behavior and the moderating role of an Islamic Work Ethic. Three hundred and thirty‐six employees in different organizations (specializing in software development, medicine, law enforcement, telecommunication, pharmaceutics, and banking) across Pakistan completed our questionnaire. The results revealed that abusive supervision was positively related to deviant workplace behavior. Moreover, the moderation of an Islamic Work Ethic on the relationship between abusive supervision and deviant work behavior was confirmed. The (...) study contributed in many ways. It expanded literature by revealing a weaker relationship between abusive supervision and deviant behavior when Islamic Work Ethic (IWE) was high. It also tested the conservation of resources theory by providing a plausible reasoning of the role of IWE in employee motivation. By integrating IWE as a resource in the workplace, practitioners would learn that the proper use of resources would produce satisfied workers who would not indulge in deviant workplace behaviors.
