Muslims are consensus on the principles of Islamic beliefs (‘usūl), though wide differences have appeared among them on the secondary beliefs (furūāt), including the infallibility (‘isma) of the prophets, especially the holy Prophet of Islam (PBUH). Some believe in the fallibility of the prophets and hence the holy Prophet of Islam, referring to some verses of the Holy Qur’an. They argue that although the prophet’s infallibility can be proved by rational reasons, rather than the words from God Almighty, as he himself took them from Him, if there are verses indicating the fallibility, then such infallibility shall be criticized and refuted through such verses. In this article, based on the analytical-citation method, different opinions on the holy Prophet’s (PBUH) immune from sin and their evidences are mentioned. In addition, the verses argued by the critics of the infallibility of the Prophet are mentioned. An investigation of the interpretations of these verses show that they not only do not indicate to this claim, but also prove the infallibility of the Holy Prophet (PBUH) at the highest level.
