Spiritual intelligence plays a strategic role in shaping students’ character and behavior, particularly in aspects of self-awareness, discipline, emotional control, and moral reasoning. However, the reinforcement of spiritual values in schools is often not systematically integrated into the learning process. Meanwhile, students’ lives in the modern era are characterized by high academic, social, and emotional pressures. The demands for achievement, grade competition, and high expectations from teachers and parents often lead to stress and emotional exhaustion. In addition, the influence of social media fosters an instant, hedonistic, and competitive culture that can weaken students’ empathy and moral character. This condition indicates the need to strengthen spiritual development so that religious values can be optimally internalized in students’ daily lives. In this context, the practice of congregational Dzuhur prayer is considered an effective strategy for developing spiritual intelligence while instilling character values. This study aims to explore the implementation of congregational Dzuhur prayer as an effort to develop students’ spiritual intelligence at SMPN 13 Surabaya. The research employs a qualitative approach with a case study design, using observation, interviews, and documentation to obtain comprehensive data. The findings show that the regular implementation of congregational Dzuhur prayer has a positive impact on improving students’ discipline, emotional control, and spiritual awareness. Furthermore, this activity helps create a religious, harmonious, and respectful school environment among all members of the school community.
