(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.

And with those who say, We are Christians, We made a covenant, but they neglected a portion of what they were reminded of, therefore We excited among them enmity and hatred to the day of resurrection; and Allah will inform them of what they did.

Has not the news of those before them come to them; of the people of Nuh and Ad and Samood, and the people of Ibrahim and the dwellers of Madyan and the overthrown cities; their messengers came to them with clear arguments; so it was not Allah Who should do them injustice, but they were unjust to themselves.

Has not the account reached you of those before you, of the people of Nuh and Ad and Samood, and those after them? None knows them but Allah. Their messengers come to them with clear arguments, but they thrust their hands into their mouths and said: Surely we deny that with which you are sent, and most surely we are in serious doubt as to that to which you invite us.

O you who believe! if an evil-doer comes to you with a report, look carefully into it, lest you harm a people in ignorance, then be sorry for what you have done.
