Sura Luqmān 31:30

ذَٰلِكَ بِأَنَّ ٱللَّـهَ هُوَ ٱلْحَقُّ وَأَنَّ مَا يَدْعُونَ مِن دُونِهِ ٱلْبَٰطِلُ وَأَنَّ ٱللَّـهَ هُوَ ٱلْعَلِىُّ ٱلْكَبِيرُ

dhālika bi-anna allāha huwa l-ḥaqqu wa-anna mā yadʿūna min dūnihi l-bāṭilu wa-anna allāha huwa l-ʿaliyyu l-kabīru

That is because Allah is the (only) Reality, and because whatever else they invoke besides Him is Falsehood; and because Allah,- He is the Most High, Most Great.
