(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.

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.

And if We make him taste mercy from Us after distress that has touched him, he would most certainly say: This is of me, and I do not think the hour will come to pass, and if I am sent back to my Lord, I shall have with Him sure good; but We will most certainly inform those who disbelieved of what they did, and We will most certainly make them taste of hard chastisement.
