The concept of "Rocon the oppressor" is one of the most important teachings of the Holy Quran in the field of social ethics and political thought of Islam, which plays a decisive role in regulating the relationship between believers and those in power. The present study was conducted in a descriptive-analytical manner with the aim of explaining the concept of support and examining the moral and social boundaries of interaction with those in power, using Quranic verses and reliable interpretative sources. The findings of the study show that support in the Quranic usage does not simply mean apparent cooperation with oppressors, but rather any heartfelt tendency, trust, support, legitimization, or participation that leads to strengthening oppression and its continuation falls within the scope of this concept. In contrast, interactions that are carried out with the aim of reform, achieving rights, preventing corruption, defending the oppressed, or securing public interests without approving of oppression are not considered examples of support. Also, a review of the relevant verses shows that the Holy Quran, while emphasizing the pursuit of justice, the moral independence of believers, and confronting oppression, introduces criteria such as maintaining justice, not consenting to oppression, denying legitimacy to the oppressor, and observing social responsibility as indicators of interaction with those in power. Accordingly, it can be concluded that the Quranic teaching of prohibiting oppression is a fundamental principle in preventing the normalization of oppression and maintaining the moral and social health of Islamic society, and can provide an efficient framework for analyzing power relations in contemporary societies.
