Surat Al-Muminoon (The Believers) - المؤمنون

مَا ٱتَّخَذَ ٱللَّهُ مِن وَلَدٍ وَمَا كَانَ مَعَهُۥ مِنْ إِلَٰهٍ إِذًا لَّذَهَبَ كُلُّ إِلَٰهٍۭ بِمَا خَلَقَ وَلَعَلَا بَعْضُهُمْ عَلَىٰ بَعْضٍ سُبْحَٰنَ ٱللَّهِ عَمَّا يَصِفُونَ ﴿٩١﴾

Never did Allah take to Himself a son, and never was there with him any (other) god-- in that case would each god have certainly taken away what he created, and some of them would certainly have overpowered others; glory be to Allah above what they describe!
