O people! be careful of (your duty to) your Lord, Who created you from a single being and created its mate of the same (kind) and spread from these two, many men and women; and be careful of (your duty to) Allah, by Whom you demand one of another (your rights), and (to) the ties of relationship; surely Allah ever watches over you.

And people are naught but a single nation, so they disagree; and had not a word already gone forth from your Lord, the matter would have certainly been decided between them in respect of that concerning which they disagree.

And if your Lord had pleased He would certainly have made people a single nation, and they shall continue to differ.
