My covenant is not within the reach of the oppressors’.
My covenant is not within the reach of the oppressors’.” (Holy Qur’an, 2:124) It is evident that such a high moral and religious position cannot be abridged or lowered to an apparent rulership or leadership, or else the verse will not hand over a reasonable meaning or sense. We believe that all the arch prophets had the dignity and grade of Imamate through their prophethood. This is because whatever they decreed by their prophethood, they put it to work as leaders..
So was the great prophet of Islam, when at the beginning of his mission he conveyed the messages of God to God’s servants, and meanwhile he carried out his leadership, teaching people and leading them to the path of truth. We believe that after the prophet Muhammad, his mission was continued by the infallible Imams who succeeded him from among his nearest kin and their offspring.
By the definitions given above, to reach the high rank of an Imam is very difficult and heavy conditions are to be observed, such as piety to the level of innocence, having the highest level of knowledge of religion and the law, and also full acquaintance with the human needs in any age or time. Imam Must Be Infallible We believe that an Imam should be free of guilt or sin.
As a matter of fact one who is not infallible, cannot be trusted to teach the realities of the law and the tenets of a divine religion. It is for his innocence that we hold an Imam's word or deed as a religious proof. Imam Is The Guardian of The Law We believe that an Imam has to know all about the roots and branches, and the commandments of Islam.
He has to know the full meanings and the exegesis of Holy Qur’an, and that he takes his knowledge from the prophet or the previous Imam; and it is such a knowledge which is trustworthy among our people (the Shi’a). Imam Must Be Appointed Openly and Clearly By The Prophet We believe that an Imam who is the successor of the prophet must be clearly and openly appointed by the Messenger of God.
An Imam's appointment also is like that of the prophet and has to be decided by God Himself .This is because the distinction of piety at the level of innocence, and such high level of knowledge required in order to allow someone to be an Imam, is at the power of God and His messenger, and no one else. We therefore do not know our Imams as those elected by the vote or choice of people.
