Although the believers are not held accountable for doing what they are not supposed to be doing due to such error of judgment, the assumption of the error of judgment itself collides with the very wisdom behind the reason why prophets were sent to people at all which is to clarify to people, according to the way God Almighty intended them to, without any error or confusion, what His Will is.

The topic of infallibility is a vast one the discussion of which has no room here and which requires a dedicated research I may be able one day to tackle.

What I have to clarify here is that Imamate is characterized by certain distinctive aspects such as infallibility which we cannot discuss by itself with others except after both parties agree on the basis from which it emerged; otherwise, our case would be like one who discusses the necessity of performing the ritual prayers (salat) with someone who does not believe in the message of the Prophet (S).

The basic point upon which we have first and foremost to agree is the definition of general Imamate, then the distinctions it requires and, finally, the proofs which testify to these distinctions. It is only then that disagreeing parties can conduct a reasonable discussion.

Having been convinced by unequivocal proofs of such infallibility, and having seen the Twelve Imams (a.s.) to be fully qualified to be the only ones in whom such infallibility could be observed, we became fully convinced of their unshakable superiority over all others, and that they were the ones adorned with absolute human perfection.

An Imam, according to this viewpoint, has got to be the most learned among people and the most aware of the general needs of people such as knowledge or other necessities of life, and that he has to be the most pious, the most ascetic, the most perfect in personal conduct and norms of behavior. In other words, in order to be qualified for Imamate, one has to be superior to everyone else in all aspects of perfection and its requirements which all raise him to his position of leadership.

On this basis, the character of Imam ar-Ridha’ (a.s.), who is one of these Twelve Imams, becomes clearly distinctive due to its merits.
