Reflection on the Arguments for the Infallibility of Imam

The most important attribute of Imam in Shiite culture and the clearest difference between Shiism and Sunni about the attributes of Imam is the infallibility of Imam. Many arguments have been presented for proving the infallibility of Imam and they have been answered by Sunni Muslims too. Examining these arguments, this research attempts to show that all of their foundation and the principle that makes them sound is that we believe a position for Imam such as the position of the prophet (pbuh), in the sense that we believe that the duty of Imam like the mission of the Prophet is the reviving of the teachings of religion, protecting and transferring them. This issue can both be as a sound principle for the proving of all the arguments and can be regarded as an independent argument for the proving of the infallibility of Imam.
