(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 be not like those who became divided and disagreed after clear arguments had come to them, and these it is that shall have a grievous chastisement.

And to Madyan (We sent) their brother Shu'aib. He said: O my people! serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord, therefore give full measure and weight and do not diminish to men their things, and do not make mischief in the land after its reform; this is better for you if you are believers:

Then did We raise up after him messengers to their people, so they came to them with clear arguments, but they would not believe in what they had rejected before; thus it is that We set seals upon the hearts of those who exceed the limits.

Certainly he led me astray from the reminder after it had come to me; and the Shaitan fails to aid man.

Those who were proud shall say to those who were deemed weak: Did we turn you away from the guidance after it had come to you? Nay, you (yourselves) were guilty

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.
