﴿ وَمَن يَدْعُ مَعَ ٱللَّهِ إِلَٰهًا ءَاخَرَ لَا بُرْهَٰنَ لَهُۥ بِهِۦ فَإِنَّمَا حِسَابُهُۥ عِندَ رَبِّهِۦٓ ۚ إِنَّهُۥ لَا يُفْلِحُ ٱلْكَٰفِرُونَ ﴾

“Hence, he who invokes, side by side with God, any other deity [- a deity] for whose existence he has no evidence - shall but find his reckoning with his Sustainer: [and,] verily, such deniers of the truth will never attain to a happy state!”
