وَهُوَ بِكُلِّ شَيْءٍ عَلِيمٌ
And He has knowledge of all things. (Qurʾān 2:29)
وَهُوَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ
And He has power over all things. (Qurʾān 5:120)
Knowledge and power are not affirmed by speculation alone. Revelation explicitly predicates them of God; a philosophical explanation must not turn these affirmations into meaningless names.
The universality of knowledge relates to everything knowable, while power concerns what is possible. A logical contradiction is not an object that could be brought into existence.
