Holiness of politics as an  attitude has been prevailed throughout the Iranian’s political history. Such a perspective enjoys some characteristics: believing in God, coordination between political and cosmic order, interrelation of religion and politics, and Divine light or chosen leader. Convincingly, foreign relations have been impressed by the belief. The current paper seeks for answer of these questions that what are the aspects of the holiness of politics view and also its effects on Iranians’view toward foreign relations.When we say Iranians, we mean Iranian Islamic thinkers.To provide a sounding answer and because of their deep effects on Islamic  Iran’political thoughts, the author has explained the nature and characteristics of the idea from three brilliant thinkers’view in Islam era,i.e Ferdowsi, Khaaje Nezamolmolk, and Khaaje Nasir. In this regard,Ferdowsi’s Shahnameh, Khaaje Nezamolmolk’s Siaaatnameh and Khaaje Nasir’s Akhlaq-e- Naseri are our selected samples.These works were studied through qualitative content analysis and their identified indices for the holiness of the politics were examined . The findings of the article prove that the holiness of politics view has turned Iran’s foreign relations as well as Iranian thinkers’ thought as a scene of dichotomy doctorine (the eternal skirmish between the Good and the Evil).
