Imam as the Source of Legislation

The Imam's authoritative place in the commandments legislation is one of the most controversial issues that had been always discussed by the scholars. Many Imami thinkers accepted this place for the Prophet, but refused to accept it for the Imam. Nevertheless, according to the denotation of some Hadiths, it seems that the purified Imams also have the authority in the Sharia commandments and, everywhere needed, can include some commandment in religion. These demonstrations consisted in: the tafwidh (cession) hadiths, the demonstrations show the affinity of the Imams with the Prophet in all the positions and the demonstrations show the occurrence of the place by the imam. With the presupposition of the Prophet's authority in the commandments legislation, the current writing tries to examine the demonstrations prove this place for the infallible Imams.
