The most important historical event in early Abbasid period was the application of the power of "reason" by Muslims; a phenomenon that was reinforced by the "Translation Movement" as well. At that time, the Imami Shi'ah was a minority group which, because of various other sects' use of "reasoning", found itself to be facing a new situation. Although at this time, the Shi'ah imams resolved different theogoy and law problems, it seems that the Shi,ah scholars had come to the conclusion that without getting involved in the Translation Movement, the preservation of the Imami Shi'ah existence would not be easy. Therefore, along with other contemporary sects such as the Mu'tazilah, the Imami Shi,ah theologians applied the power of reason and intellect in their theological arguments. This article deals with those early Imami Shi'ah theologians who through their debates and writings played a major role in saving the Imami Shi'ah school.
