Introduction: The present research analyzes the role of mosques as the most widespread, pervasive social network and examines their place in district development in Holy Mashhad. The analysis is done through investigating the variables related to the multifold activities of mosques in neighborhoods and evaluating neighborhood dweller’s reception of activities and programs offered and foundations laid by mosques. The variables related to the multifold activities of mosques pivot on eight general points (i.e., the role of mosques in enriching people’s free time, creation of a cultural atmosphere, offering financial aides, staging religious-cultural ceremonies and meetings, increasing the participation rate of neighborhood dwellers, offering consultation, prioritizing neighborhoods’ issues, problems and needs, and enhancing individual and social security through increased internal and external surveillance).
