This book explores the acknowledgment of Imam Ali Ibn Abi Talib (a.s.) by the United Nations, particularly in the context of his just and humane leadership as a ruler of the Islamic world. The UN has recognized the governance model of Imam Ali as an exemplar of fairness, equity, and the protection of human rights. This book examines his letters, especially the famous Letter to Malik al-Ashtar, and other teachings that promote social justice, welfare, and the well-being of citizens regardless of religion or ethnicity. The book also delves into how these principles resonate with the modern concepts of governance and human rights, making Imam Ali’s legacy timeless and universally relevant.
