We will say: It is not necessary that the said shortcoming be disbelief (Kufr) or a great sin. He did not believe that the Imam is not his Imam, nor did he threaten his life. He merely failed to understand certain things. Like a cause that this doubt in Imamate will occur from him in future and has not occurred so far. Thus, he is not necessarily a disbeliever, or like a person who considers the Imam a liar or doubts his truthfulness. It is a sin and a mistake that does not negate belief and merits for rewards. The devotee of the Imam does not go into the same category as his enemy in this case, because the enemy holds an opinion about the Imam, which amounts to disbelief and a major sin, and the devotee is opposite to that. We said that what is “like a cause” for disbelief is not necessarily disbelief at this stage, because if one of us believes that he is an independent cause with respect to other objects, it will be ignorance and mistake, but not disbelief (Kufr).
