And He it is Who sends forth the winds bearing good news before His mercy, until, when they bring up a laden cloud, We drive it to a dead land, then We send down water on it, then bring forth with it of fruits of all kinds; thus shall We bring forth the dead that you 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.
