Tenets of Islam

Infallibility

All Prophets were infallible and free from all defects, sins, and negligence and forgetfulness in their deeds and sayings from their early childhood till their death, for if they had committed a sin or a mistake, they would have lost their position in the hearts of the people who would not have had confidence in what they said or did. In this way the benefits of Prophethood would have come to naught. Therefore certain stories mentioned about them in the Holy Qur'an must be explained away.

The Prophets (peace be on them) must be the best and the most learned men of their time, for it is absurd to give preference to the inferior people.
