Civilization is grounded not only in material achievements and political and economic structures but also in a particular form of human and social life. From this perspective, civilizational development can be examined through “civilized life,” understood as a way of life in which individuals organize their personal and social relations according to fundamental values, thereby creating the conditions for a cohesive and just society with civilizational capacity. This study aims to elucidate the model of civilized life in the intellectual framework of Imam Ali (A.S.) and examine its relationship with the New Islamic Civilization. It asks what the fundamental components of civilized life in Nahj al-Balagha are and how they extend from human development to community-building and civilizational development. The study is fundamental in terms of its objective and employs a qualitative analytical-inferential approach, using qualitative thematic analysis through an exploratory-inductive strategy and interpretive organization of themes. The findings indicate that civilized life can be conceptualized at four levels: human, social relations, institutions, and civilization. These levels encompass five major categories: human dignity and development; rationality and piety; justice and adherence to rights; social responsibility and sound governance; and knowledge, production, and development directed toward the public good. The study concludes that human beings are not merely objects of moral cultivation but responsible agents capable of contributing to civilizational development. Society acquires civilizational capacity when these principles are reflected and institutionalized in social relations and political and economic institutions.
