1. The Successor of the Prophet
The Shi‘a Ithnā `Ashari Muslims believe that after the Prophet of Islam, the leadership of the world of Islam fell to Amir al-Mu’minin, ‘Ali (a.s.), and then to his eleven infallible descendants. This belief is as clear as the rays of the morning sun, and those who are unprejudiced and impartial will have no cause to doubt it.
