In the period of Minor Occultation, theologians like Ibn Qube Razi, Newbakhtis, al-Shaykh al-Mufid, Seyyed Morteza and al-Shaykh al-Tusi rebuild the theological school of Imamiyah. In the second and third century of Hijra, a Ma'sum (infallible) and divinely chosen leader of the religion was more focused than the political role of the Imams by the theologians. Although Imamiyah believed that most of the works on the early Islamic centuries argue that Shi'ism began as a political movement rather than a religious group. However this does not mean that religious sentiments were absent in the first century.
