مَا اتَّخَذَ اللّٰهُ مِنْ وَّلَدٍ وَّمَا كَانَ مَعَهٗ مِنْ اِلٰهٍ اِذًا لَّذَهَبَ كُلُّ اِلٰهٍۢ بِمَا خَلَقَ وَلَعَلَا بَعْضُهُمْ عَلٰى بَعْضٍۗ سُبْحٰنَ اللّٰهِ عَمَّا يَصِفُوْنَ ۙ ( المؤمنون: ٩١ )
Mat takhazal laahu minw waladinw wa maa kaana ma'ahoo min ilaah; izal lazahaba kullu ilaahim bimaa khalaqa wa la'alaa ba'duhum 'alaa ba'd; Subhaannal laahi 'ammaa yasifoon (al-Muʾminūn 23:91)
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]. (Al-Mu'minun  : 91)

Allah has not taken a son to Himself, nor was there any god with Him. Had there been so, every god would have taken away what he created, and each one of them would have been aggressive against the other. Pure is Allah from what they describe.
