Shiavault - a Vault of Shia Islamic Books The Infallibility of the Prophets in the Qur'an Why ‘Ismah? The prophets have to be ma'sum for the same reason for which they were sent: to guide and lead the people towards God. God, who decided to guide mankind, also intended to send immaculate and perfect human beings as models and examples. If they were not ma'sum , then it would have been extremely difficult even to believe in the message let alone the example they present to us.
There would be no trust or confidence in whatever they say: it could be true; it could be false. Sending fallible prophets would have defeated the very purpose for which they were sent: for the prophets to lead and guide, for the people to follow and obey. * * * The Qur'an also supports this reasoning.
Besides these verses, there are also many verses where Allah describes the virtue of obeying the prophets, and the dire consequences of disobeying them.[^1] Secondly, in most such verses, Allah has mentioned obedience to Himself alongside with the obedience to His messengers.
Otherwise, we would have found ourselves in an impossible situation: a non- ma'sum prophet or messenger exhorts us to do something which is wrong—should we follow or not.
