Allah’s, s.v.t., messengers are His chosen slaves whom He has chosen to be the mediators between Him and His creatures and has shown them special honor by sending them revelation. Despite being human beings, they were with the greatest knowledge of Allah, worship and the greatest piety, and therefore they deserved to carry the emanation of the transmission of the faith. Allah, aza wa jal, has not left any nation without sending them a Prophet or someone who will convey a Prophethood to them, from the good people who followed their path. Allah, the Exalted, says: It is yours to warn, and every nation had one who guided it to the Right Path. (Er-Rad, 7.)

And there was no people to whom the one who warned him did not come. (Fatir, 24)
