One of the most important issues in Islamic theology is the scope of Infallibility of the Prophet of Islam (S.A.W.). The Asha’arites believe that the Holy Prophet (S.A.W.) was only Infallible after his prophethood and just in committing major sins. On the contrary, the Mu'tazilites believe in the Infallibility of the Holy Prophet before the prophethood as well. But they do not consider committing minor sins in regard to the affairs not concerning religion, in conflict with the infallibility. According to Shi’a, the holy Prophet was free of sins and mistakes from his birth time till his death. This definition of Infallibility is called absolute infallibility (infallibility in action, talks, and thoughts). In this writing, the viewpoints of the Mu'tazilites and Ash'arites have been criticized and the viewpoint of the Shi’as has been explained.
