Quran 23:90 — The Believers (Al-Mu'minun)

We have given them the truth, while they are liars.

[23:89] They will say, "GOD." Say, "Where did you go wrong?"

[23:91] GOD has never begotten a son. Nor was there ever any other god beside Him. Otherwise, each god would have declared independence with his creations, and they would have competed with each other for dominance. GOD be glorified; far above their claims.
