Imam Ali (PBUH) in his period of government (Khalifate) displayed a leadership model based on social justice and real acknowledgement of human rights. Once he appointed one of his faithful disciples as the Governor of Egypt. Maalik al-Ashtar was a famous companion of Imam Ali and Imam had specially taught him the principles of administration and jurisprudence. The following instructions in the form of a letter were written to him by Imam Ali when he left for Egypt. The letter is a comprehensive set of political, social, economic and moral instructions for a governor to rule with honesty, fairness, and equality.
