Surely those who conceal the clear proofs and the guidance that We revealed after We made it clear in the Book for men, these it is whom Allah shall curse, and those who curse shall curse them (too).

(All) people are a single nation; so Allah raised prophets as bearers of good news and as warners, and He revealed with them the Book with truth, that it might judge between people in that in which they differed; and none but the very people who were given it differed about it after clear arguments had come to them, revolting among themselves; so Allah has guided by His will those who believe to the truth about which they differed and Allah guides whom He pleases to the right path.

How shall Allah guide a people who disbelieved after their believing and (after) they had borne witness that the Messenger was true and clear arguments had come to them; and Allah does not guide the unjust people.

And whoever acts hostilely to the Messenger after that guidance has become manifest to him, and follows other than the way of the believers, We will turn him to that to which he has (himself) turned and make him enter hell; and it is an evil resort.

It is not (attributable to) Allah that He should lead a people astray after He has guided them; He even makes clear to them what they should guard against; surely Allah knows all things.

They said: O our people! we have listened to a Book revealed after Musa verifying that which is before it, guiding to the truth and to a right path:

Surely (as for) those who return on their backs after that guidance has become manifest to them, the Shaitan has made it a light matter to them; and He gives them respite.

Surely those who disbelieve and turn away from Allah's way and oppose the Messenger after that guidance has become clear to them cannot harm Allah in any way, and He will make null their deeds.
