Qur'an 39:3

أَلَا لِلَّهِ ٱلدِّينُ ٱلْخَالِصُ ۚ وَٱلَّذِينَ ٱتَّخَذُوا۟ مِن دُونِهِۦٓ أَوْلِيَآءَ مَا نَعْبُدُهُمْ إِلَّا لِيُقَرِّبُونَآ إِلَى ٱللَّهِ زُلْفَىٰٓ إِنَّ ٱللَّهَ يَحْكُمُ بَيْنَهُمْ فِى مَا هُمْ فِيهِ يَخْتَلِفُونَ ۗ إِنَّ ٱللَّهَ لَا يَهْدِى مَنْ هُوَ كَـٰذِبٌ كَفَّارٌ

“Unquestionably, for Allāh is the pure religion. And those who take protectors besides Him [say], "We only worship them that they may bring us nearer to Allāh in position." Indeed, Allāh will judge between them concerning that over which they differ. Indeed, Allāh does not guide he who is a liar and [confirmed] disbeliever.”
