And when those who believe in Our communications come to you, say: Peace be on you, your Lord has ordained mercy on Himself, (so) that if any one of you does evil in ignorance, then turns after that and acts aright, then He is Forgiving, Merciful.

These are they who disbelieve in the communications of their Lord and His meeting, so their deeds become null, and therefore We will not set up a balance for them on the day of resurrection.

And say: Praise be to Allah, He will show you His signs so that you shall recognize them; nor is your Lord heedless of what you do.
