The Imam’s Knowledge from a Logical Point of View
The main goal of Prophet Muhammad’s (s) mission was training and refining humans. In addition to reciting and teaching the Holy Quran, the Messenger of Allah (s) interpreted Quranic verses and explained vague points when necessary. He mentioned transformer and obsolete, general and specific, absolute and conditional verses. He presented religious commandments and rules that he obtained from revelation to the people. He spread true beliefs and fought superstition and wrong ideas. He invited the people to moral virtues and prohibited from vices. He had necessary knowledge about all these teachings and sciences from revelation or logic; hence he could accomplish these duties well, directing his followers to the right path.
The Imam, who is the successor to the Prophet (s) and continues his path, should possess all these sciences to be able to fulfill his responsibilities; otherwise there will be no valid guarantee for continuation of religion. In other words, the Imam should have all the sciences of the Prophet (s), except that the Prophet gets them directly via the Divine revelation but the Imam gets them from the Prophet (s).
