Allah is the most powerful and He nor does have a wife or a son. Those who ascribe anything one or anything with Allah is a disbeliever. The truth about Allah has been mentioned numerous times in the Holy Quran.

“Nay, we fling send down the truth (this Quran) against the falsehood (disbelief), so it destroys it, and behold, it (falsehood) is vanished. And woe to you for that (lie) which you ascribe (to Allah by uttering that Allah has a wife or a son).”
Quran (Surah Al-Anbiya, 18)
