The issue of popular participation in governance from the perspective of Imam Khamenei's (Ayatollah Seyyed Ali) Quranic thoughts is considered as a fundamental pillar of the stability and development of the Islamic system. The present study, by posing the question, "Based on the Quranic thoughts of Imam Khamenei (Ayatollah Seyyed Ali), what are the dimensions and components of popular participation in religious governance and how can they be explained within the theoretical framework of religious governance?", has addressed the conceptual explanation and structural analysis of participation. The aim is to identify and explain the mechanisms for strengthening public participation in the social, political, cultural, security, economic, and educational fields and its strengthening capacities from the perspective of the Quran and the statements of the Supreme Leader. This research was conducted with a qualitative approach and using the content analysis method. The data under study were extracted from the statements and messages of the Leader of the Revolution in the last three decades and then analyzed through a coding process. The findings showed that popular participation, both in the field of social reconstruction and construction and in the political arena, as a religious duty, is the cause of maintaining the country's independence, the insurer of the Islamic Revolution and the factor of national excellence. Its strengthening depends on education, creating infrastructure and institutionalizing a culture of responsibility. Finally, the research suggests implementation mechanisms and solutions to remove obstacles and points out limitations such as focusing on qualitative data and the lack of field surveys.
