One of the hesitations and challenges facing the divine prophets and Shiite Imams is that their infallibility does not seem to fit in with the human choice. Is not committing sin or error, whether intentional or unintentional, whether a petty misdemeanor or a grave sin (which is a belief of ImamiShiite), throughout their lifetime, mean in a way contradictory with their choice as a human? The Ulema and Islamic scholars have provided solutions as response and rational and logical explanation. Amongst such solutions are providing a comprehensive and complete explanation and interpretation to resolve such conflict, the argument for coercive force of infallibility, the argument for not having their own right to do good deeds, and the argument for their immunity for their duties towards God, etc.What we consider here as a solution to the conflict of Infallibility and its coercive connotations, is the explanation of such a riddle, that is considering the nature and truth of infallibility, for finding about the immunity of the infallible Imams.
