Allah the Creator has not only brought about the creation, but continues to sustain and direct it, in the way that He has created us and all that is around us. He has provided many forms of guidance, indeed, a system of guiding principles, of which the laws of 'nature' are a part.

But Allah has also granted a special form of guidance for mankind from the outset of its occupancy of the earth. He promised to Adam and his descendants: 'Get ye down all from here; and if, as is sure, there comes to you guidance from Me, whosoever follows guidance, on them shall be no fear, nor shall they grieve' (2: 38).' [The word here used for guidance is hudan.] This guidance comes through the prophets, whom Allah continuously sent to mankind, until the last messenger, Muhammad received His final guidance.

We call a man to whom God in his own way communicates His guidance, a prophet or messenger (nabi, rasul). Prophets receive the word of God through revelation and then communicate it to their fellow human beings: 'We have sent thee INSPIRATION, as We sent it to Noah and the messengers after him: We sent INSPIRATION to Abraham, Ismail, Isaac, Jacob and the tribes, to Jesus, Job, Jonah, Harun and Solomon, and to David We gave the Psalms. Of some apostles, We have already told the story, of others We have not and to Moses God spoke direct apostles who gave good news as well as warning, that mankind after (the coming) of the apostles should have no plea against God: for God is exalted in power and ways' ().
