Luqman - 31:30

ذَلِكَ بِأَنَّ اللَّهَ هُوَ الْحَقُّ وَأَنَّ مَا يَدْعُونَ مِن دُونِهِ الْبَاطِلُ وَأَنَّ اللَّهَ هُوَ الْعَلِيُّ الْكَبِيرُ
[31:30]
This is because Allah is the Truth, and that which they call upon besides Him is the falsehood, and that Allah is the High, the Great.
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.
That (is so) because Allah, He is the True, and that which they invoke beside Him is the False, and because Allah, He is the Sublime, the Great.
