(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.

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

It is not (fit) for the Prophet and those who believe that they should ask forgiveness for the polytheists, even though they should be near relatives, after it has become clear to them that they are inmates of the flaming fire.
