﴿ ذَٰلِكَ بِأَنَّ ٱللَّهَ هُوَ ٱلْحَقُّ وَأَنَّ مَا يَدْعُونَ مِن دُونِهِ ٱلْبَٰطِلُ وَأَنَّ ٱللَّهَ هُوَ ٱلْعَلِىُّ ٱلْكَبِيرُ ﴾

“Thus it is, because God alone is the Ultimate Truth, so that all that men invoke instead of Him is sheer falsehood; and because God alone is exalted, truly great!”

That which is mentioned is so because God He is the Truth the established truth and whatever they call on read yad‘ūna; or tad‘ūna ‘you call on’ whatever they worship besides Him is evanescent falsehood and because God is the High Exalted above His creation by virtue of His subjugation of them the Great the Mighty.
