According to the Quran, God communicated with man and made his will known through signs and revelations. Prophets, or 'Messengers of God', received revelations and delivered them to humanity. The message has been identical and for all humankind. "Nothing is said to you that was not said to the messengers before you, that your lord has at his Command forgiveness as well as a most Grievous Penalty." The revelation does not come directly from God to the prophets. Angels acting as God's messengers deliver the divine revelation to them. This comes out in Quran 42:51, in which it is stated: "It is not for any mortal that God should speak to them, except by revelation, or from behind a veil, or by sending a messenger to reveal by his permission whatsoever He will."
Which part of the Quran describes God's use of intermediaries between himself and his prophets?
