This comparative study examines the qualities of leadership from two distinct perspectives: Imam Ali's renowned Letter 53 and New Management. The goal of the study is to compare and contrast the two techniques, notwithstanding the distinct historical and cultural settings in which each methodology originated. Also, this essay describes the core values of the new management, which include maximizing efficiency, customer satisfaction, innovation, quality assurance, productivity growth, and employee empowerment. In the same spirit, Imam Ali's leadership principles—including delegation, active listening, informed decision-making, tolerance, empathy, and respect—are presented. After a comparison of the similarities and differences between the two methodologies, we study these traits in-depth and talk about their individual benefits and drawbacks in connection to the various scenarios. Also, we point out the parallels and discrepancies between these two leadership philosophies, notably in terms of delegating, judgment, and empathy. We finish this comparison research by reflecting on the article's application in the real world and discussing how managers and leaders may use both approaches to create their own leadership styles. We also discuss future directions for leadership research by taking Imam Ali's teachings into account. In light of this comparison, our study offers an in-depth analysis of two leadership methods and their points of convergence and divergence, with the aim of enriching contemporary leadership thinking and highlighting the legacy of Imam Ali.
