This article comprehensively analyzes the concept of the “ideal ruler” developed by one of the founders of Islamic philosophical heritage, Abu Nasr al-Farabi. According to al-Farabi, the ultimate goal of society is for human beings to achieve supreme happiness (as-sa‘āda al-quṣwā), which can only be realized under the leadership of a ruler endowed with wisdom, knowledge, and justice. The “prophet-philosopher” model proposed by al-Farabi represents both a continuation of Plato’s “philosopher-king” concept and a new interpretation enriched with Islamic moral and metaphysical values. The article systematically examines the epistemological harmony established by al-Farabi between reason and revelation, as well as the intellectual, ethical, and spiritual qualities of the ruler. Al-Farabi’s conception of the ideal ruler is grounded both in rational knowledge and in divine wisdom. It emphasizes that within the concept of the virtuous city, the ruler plays a decisive role: he is not merely a governing authority, but also the principal pillar safeguarding the moral unity of society and upholding the principle of justice. The study concludes that al-Farabi’s conception of the ideal ruler retains its contemporary relevance, demonstrating significant correspondence with modern ethical and transformational leadership theories.
