Surah Al-Hajj (The Pilgrimage), Verse 62

ذٰلِكَ بِاَنَّ اللّٰهَ هُوَ الْحَقُّ وَاَنَّ مَا یَدْعُوْنَ مِنْ دُوْنِهٖ هُوَ الْبَاطِلُ وَاَنَّ اللّٰهَ هُوَ الْعَلِیُّ الْكَبِیْرُ ۟

Zaalika bi annal laaha Huwal haqqu wa anna maa yad'oona min doonihee huwal baatilu wa annal laaha Huwal 'Aliyyul kabeer

“That is because Allah - He is the Reality; and those besides Him whom they invoke,- they are but vain Falsehood: verily Allah is He, Most High, Most Great.”
