Surah Al-Hajj, Verse 62

ذَٰلِكَ بِأَنَّ ٱللَّهَ هُوَ ٱلۡحَقُّ وَأَنَّ مَا يَدۡعُونَ مِن دُونِهِۦ هُوَ ٱلۡبَٰطِلُ وَأَنَّ ٱللَّهَ هُوَ ٱلۡعَلِيُّ ٱلۡكَبِيرُ٦٢

dhālika bi-anna l-laha huwa l-ḥaqu wa-anna mā yadʿūna min dūnihi huwa l-bāṭilu wa-anna l-laha huwa l-ʿaliyu l-kabīru

That is because Allāh is the True Reality, and that which they call upon other than Him is falsehood, and because Allāh is the Most High, the Grand.
