That is Allah, your Lord, Creator of all things; there is no deity except Him, so how are you deluded?
The Saheeh International Quran Translation
ذَٰلِكُمُ ٱللَّهُ رَبُّكُمْ خَٰلِقُ كُلِّ شَىْءٍ لَّآ إِلَٰهَ إِلَّا هُوَ فَأَنَّىٰ تُؤْفَكُونَThat is Allah, your Lord, Creator of all things; there is no deity except Him, so how are you deluded?
