And it is all the same for them whether you warn them or do not warn them- they will not believe. You can only warn one who follows the message and fears the Most Merciful unseen. So give him good tidings of forgiveness and noble reward. Indeed, it is We who bring the dead to life and record what they have put forth and what they left behind, and all things We have enumerated in a clear register.
THE QUR'AN, Ya Seen 36:10-12
