"And We have made before them a barrier and a barrier behind them, then We have covered them over so that they do not see.
And it is alike to them whether you warn them or warn them not: they do not believe.
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.
erily We shall give life to the dead, and We record that which they send before and that which they leave behind, and of all things have We taken account in a clear Book (of evidence).
[Ya-Seen: 9-12]
