Al-Mu'minun (The Believers)
Surah 23 · Verse 91
Allah has not taken any son nor is there any (other) god with Him, (had there been two or more gods, then) in that case, each god would have taken away that which he had created and some would have dominated over others, glorified be Allah above that which they describe,
Allah (SWT) does not have a son and there is no god or any authority in the universe, other than Him. It is a matter of common sense that if there were two or more gods or authorities in the universe each would have had control on that which it had created and some would have tried to dominate the others. Allah (SWT) is the Knower of everything and He is the Supreme Authority in the Universe. See Chapter:17 Verse 42, Chapter:21 Verse 22 also.
