This study explores the complex dynamics of celebration in these two well-known mosques. Our main goal is to provide a thorough comparative study, investigating the connections between religious rituals, social gatherings, and cultural celebrations in these various religious settings. By utilizing a mixed-methods approach that includes questionnaires, interviews, and on-site observations, we want to identify distinctive trends and variances in the festivities that take place at the Al-Shorta and Sayyida Nafisa mosques. According to preliminary results, these mosque communities' identities are shaped by a variety of religious rites, social interactions, and cultural events. This study adds to our knowledge of the crucial role mosques play in community dynamics and has implications for promoting harmony and protecting cultural heritage. By comparing and contrasting the two, the research seeks to shed light on how these festivals affect social cohesiveness and cultural preservation. By recognizing the importance of religious, social, and cultural factors, this study aims to improve the conversation about community life that revolves around mosques. Our findings may influence research in the future, direct community development programs, and foster cross-cultural understanding, underscoring the significance of these festivities in forming the cohesiveness and cultural legacy of Egyptian mosque communities.
