This article deals with a comparative study of the views of the Quran and the Gospels on the principle of “good versus evil.” The aim of this research is to analyze and compare the teachings of these two religious sources on responding to the undesirable actions of others and to present a comprehensive picture of different approaches in confronting evil. This research, using the comparative content analysis method, has examined and compared the views of the Quran and the Gospels on good versus evil. The data have been extracted from the original texts of the Quran and the Gospels and examined with an analytical-critical approach. The findings show that both sources emphasize goodness in response to the evil of others. However, fundamental differences in their approaches are evident. The Gospels emphasize absolute goodness and non-resistance to evil, while the Quran, while recommending goodness in response to evil, emphasizes the need to implement justice and confront oppression within the framework of protecting the rights of individuals and the interests of society. By examining the scope and scope, wisdom, limits, and conditions of goodness in response to evil from the perspectives of the Quran and the Gospels, this article shows that the Quran, by presenting a balanced, more comprehensive, and more consistent approach with the requirements of individual and social life, presents a more complete and wise picture of the concept of goodness in response to evil. This is while the Gospels emphasize more on the individual and spiritual aspects of this principle and less on its social and legal aspects.
