(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 do not marry the idolatresses until they believe, and certainly a believing maid is better than an idolatress woman, even though she should please you; and do not give (believing women) in marriage to idolaters until they believe, and certainly a believing servant is better than an idolater, even though he should please you; these invite to the fire, and Allah invites to the garden and to forgiveness by His will, and makes clear His communications to men, that they may be mindful.
