Authentic and transformative leadership based on Islamic values ​​is one of the fundamental pillars of the sustainability and excellence of the Islamic society. In the current situation where corruption, profiteering, and moral weakness threaten many management structures, returning to principles such as honesty, simplicity, justice, and selfless service to the people is a fundamental necessity. The main question of this research is how authentic and transformative leadership based on Islamic values ​​and the thoughts of the Supreme Leader can provide a basis for social trust, national cohesion, and organizational excellence? According to the research hypothesis, if the leadership model in Iran is formed based on sincerity of intention, justice, self-awareness, empathy, and practical commitment to divine values, the result will be to strengthen social capital, increase the efficiency of organizations, and move toward a monotheistic society. The study of the thoughts of Imam Khomeini (RA) and the Supreme Leader shows that authentic leadership with honesty, simplicity, and people-orientedness restores social trust, and transformational leadership opens the path to the excellence of society by drawing a divine vision and mobilizing social forces. As a result, the realization of Islamic management requires simultaneous attention to the two dimensions of authenticity and transformation; the authenticity dimension guarantees legitimacy and public trust, and the transformational dimension leads society towards modernization, progress, and responsiveness to the needs of today and the future.
