Unforgiven

Whether you seek forgiveness for them or not, even if you ask seventy times, Allah will never forgive them. That is because they rejected Allah and His Messenger.

9:80Ask forgiveness for them (O Muhammad), or ask not forgiveness for them; though thou ask forgiveness for them seventy times Allah will not forgive them. That is because they disbelieved in Allah and His messenger, and Allah guideth not wrongdoing folk.

Those who disbelieve and persist in wrongdoing, Allah will never forgive them nor guide them to any path

4:168Lo! those who disbelieve and deal in wrong, Allah will never forgive them, neither will He guide them unto a road,

Except the path to Hell

4:169Except the road of hell, wherein they will abide for ever. And that is ever easy for Allah.
