Hawzah News Agency- History indicates that there were prophets among people who responded to the call of Allah; however, the details of their life are not so clear. Only the details of life of Prophet Muhammad (S) are devoid of ambiguity. The Holy Qur'an, which is the divine book given to Prophet (S), contains sublime religious aims, has clarified the call of the prophets in the past and has described their goals and objectives.
 

The Holy Qur'an stipulates that many prophets have been, assigned by Allah to lead the people, all of whom consistently invited the people to monotheism and the true religion. As Allah states:
"And We did not send before you any messenger but We revealed to him that
there is no god but Me, therefore worship Me (21:25)."
