This study sought to explore the philosophical approach to religious asceticism in the three Abrahamic religions (i.e. Christianity, Judaism and Islam). The research focused on providing the similarities and differences in ascetic practices among the three religions. Essentially, the study aimed at providing the most philosophically accepted view on asceticism in these religions. A secondary research approach was employed in order to achieve the study objectives. The research design used involved a review of literature regarding various aspects of religious asceticism practiced in Abrahamic faith traditions. To study the phenomenon, a total number of 20 peer-reviewed journal articles (n=20) were used. The findings of this study revealed that significant similarities and differences occur in the way these religions practiced asceticism. Additionally, the results obtained showed that most ascetic practices adopted by Abrahamic faith religions did not exist in other non-Abrahamic religions. The findings of the current research were significant in understanding religious asceticism as well as the practice. While only a few sources were used in the current study, future research should provide a broad perspective into the phenomenon by examining a large set of sources as well as investigating asceticism in other religions in addition to the three Abrahamic
