According to the Twelve-Imam Shi’ism (Imamiyyah), the Imamate is one of the fundamentals of Islam and that man's faith can never be completed without belief in it. According to them, the Imams have authority, and Allah has ordered people to obey them. They are witnesses for mankind, doors opening the way of Allah, guides to Him, guardians of His knowledge, interpreters of His revelation, pillars of His Unity and custodians of His Wisdom. The reason for this is the same as that which we gave to the prophet's superiority. He derives his education, the Divine commandments and all his knowledge from the Prophet or from the previous Imam. When a new question arises, he knows the answer from Divine Inspiration through the pure mind that Allah has given him. If he gives attention to some matters in order to know them, he will obtain a perfect understanding with no error, for the Imams do not derive their knowledge from methodological reasoning, or from the teachings of men of knowledge, although it is possible for their knowledge to be increased and strengthened. Therefore in this article we tried to investigate the doctrine of knowledge attributed to the Imam on the basis of the Shi'ite view of religious scholars.
