Participation is one of the most critical manifestations of humanity and morals that displays responsibility, conscious and free action. Social participation is one of the resources available in social interactions. Therefore, the expansion of actions and the study of actors' goals to achieve good is not collective. From this point of view, social participation is the creation of social capital in society. Social capital also is not realized except by manifesting indicators such as trust and the institutional bond between individuals resulting from the group, social interactions, and norms. Imam Ali (AS) considers the principle of participation as an obligatory concept. Therefore, in this article, using the descriptive-analytical method, we will study the importance of social participation as social capital based on Nahj al-Balaghah and its interpretation and analysis according to Imam Ali (As).
