(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 (make him) a messenger to the children of Israel: That I have come to you with a sign from your Lord, that I determine for you out of dust like the form of a bird, then I breathe into it and it becomes a bird with Allah's permission and I heal the blind and the leprous, and bring the dead to life with Allah's permission and I inform you of what you should eat and what you should store in your houses; most surely there is a sign in this for you, if you are believers.

And We have revealed to you the Book with the truth, verifying what is before it of the Book and a guardian over it, therefore judge between them by what Allah has revealed, and do not follow their low desires (to turn away) from the truth that has come to you; for every one of you did We appoint a law and a way, and if Allah had pleased He would have made you (all) a single people, but that He might try you in what He gave you, therefore strive with one another to hasten to virtuous deeds; to Allah is your return, of all (of you), so He will let you know that in which you differed;

So they have indeed rejected the truth when it came to them; therefore the truth of what they mocked at will shine upon them.

These towns-- We relate to you some of their stories, and certainly their messengers came to them with clear arguments, but they would not believe in what they rejected at first; thus does Allah set a seal over the hearts of the unbelievers
