Qur'ān 23:91 · Al-Mu'minun (المؤمنون)
مَا ٱتَّخَذَ ٱللَّهُ مِن وَلَدٍۢ وَمَا كَانَ مَعَهُۥ مِنْ إِلَـٰهٍ ۚ إِذًۭا لَّذَهَبَ كُلُّ إِلَـٰهٍۭ بِمَا خَلَقَ وَلَعَلَا بَعْضُهُمْ عَلَىٰ بَعْضٍۢ ۚ سُبْحَـٰنَ ٱللَّهِ عَمَّا يَصِفُونَ
Allah has not taken any son, nor has there ever been with Him any deity. [If there had been], then each deity would have taken what it created, and some of them would have sought to overcome others. Exalted is Allah above what they describe [concerning Him].
