Achieving an “Islamic civilization”, as the transcendent goal of Islamic society, has a direct relationship with the issue of “Mahdism. The epistemological foundations of “Mahdism” as the “guiding star”, guide the Islamic societies to a perfect society profiting an ideal civilization by drawing an achievable future. The “revolutionary awaiting”, which was raised after the victory of Islamic Revolution, has chosen the establishment of a new Islamic civilization as its main goal to prepare the ground for the appearance of the Imam of the Time (A.S). The present study, with a descriptive-analytic method, at first deals with the scientific typology of different kinds of “active awaiting” (ritual, military and revolutionary) and then, explains the intellectual system of Ayatollah Khamenei in relation to the revolutionary active awaiting and its relationship with the civilization. And finally, by focusing on the “awaiting person”, it tries to draw and introduce a conceptual model based on the course of the stages of ‘humanization”, ‘religious socialization” and “nation-building” in order to achieve a ‘new Islamic civilization”.
