Isma‘ilian philosopher Hamid al-Din Kermani (d.411 H.) has played a considerable role in establishing and completing Isma‘ilian philosophical opinions and in describing theological principles of Fatemian. Reproposing the imamate of Fatemi Imams and the connection of the lowest state of being and embodiment of earthly degrees of Imam with the degrees of being and creation have been known to be his bold properties of thought. The questions of this paper run as: how did Hamid al-Din theorize and rethink Isma‘ilian concept of imamate and principles of thought.And what can be counted as the consequences of his action? Accordingly the hypothesis of the paper consists in: Hamid al-Din, presenting a combined and comparative semi-proposal with an interpretative approach, a reasonable foundation and a philosophical essence, sought to reconsider Isma‘ilian principles of thought and offered an organized proposal for Isma‘ilian theological principles centering on Fatemi Imam.
