Surah Al-Mu'minun (The Believers), Verse 117

وَمَنْ یَّدْعُ مَعَ اللّٰهِ اِلٰهًا اٰخَرَ لَا بُرْهَانَ لَهٗ بِهٖ فَاِنَّمَا حِسَابُهٗ عِنْدَ رَبِّهٖ اِنَّهٗ لَا یُفْلِحُ الْكٰفِرُوْنَ ۟

Wa mai yad'u ma'allaahi ilaahan aakhara laa burhaana lahoo bihee fa inna maa hisaabuhoo 'inda Rabbih; innahoo laa yuflihul kaafiroon

“If anyone invokes, besides Allah, Any other god, he has no authority therefor; and his reckoning will be only with his Lord! and verily the Unbelievers will fail to win through!”
