(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 We gave them clear arguments in the affair, but they did not differ until after knowledge had come to them out of envy among themselves; surely your -Lord will judge between them on the day of resurrection concerning that wherein they differed.

O you who believe! do not take My enemy and your enemy for friends: would you offer them love while they deny what has come to you of the truth, driving out the Messenger and yourselves because you believe in Allah, your Lord? If you go forth struggling hard in My path and seeking My pleasure, would you manifest love to them? And I know what you conceal and what you manifest; and whoever of you does this, he indeed has gone astray from the straight path.
