Qur'ān 23:117 · Al-Mu'minun (المؤمنون)

وَمَن يَدْعُ مَعَ ٱللَّهِ إِلَـٰهًا ءَاخَرَ لَا بُرْهَـٰنَ لَهُۥ بِهِۦ فَإِنَّمَا حِسَابُهُۥ عِندَ رَبِّهِۦٓ ۚ إِنَّهُۥ لَا يُفْلِحُ ٱلْكَـٰفِرُونَ

And whoever invokes besides Allah another deity for which he has no proof - then his account is only with his Lord. Indeed, the disbelievers will not succeed.
