The Twelve Imams are the spiritual and political successors to Muhammad, the Prophet of Islam, in the Twelver or Ithna-‘ashariyyah branch of Shi‘ah Islam. According to the theology of Twelvers, the successor of Muhammad is an infallible human individual who not only rules over the community with justice, but also is able to keep and interpret the Divine Law and its esoteric meaning. The Prophet and Imams' words and deeds are a guide and model for the community to follow; as a result, they must be free from error and sin, and must be chosen by divine decree, or nass, through the Prophet. It is believed by Twelver Shi'a Muslims that the Twelve Imams were foretold in the Hadith of the Twelve Successors.
