What! do you wonder that a reminder has come to you from your Lord through a man from among you, that he might warn you and that you might guard (against evil) and so that mercy may be shown to you?

And you were not on this side of the mountain when We called, but a mercy from your Lord that you may warn a people to whom no warner came before you, that they may be mindful.

You can only warn him who follows the reminder and fears the Beneficent Allah in secret; so announce to him forgiveness and an honorable reward.
