Quran 39:3 — The Throngs (Al-Zumar)

أَلا لِلَّهِ الدّينُ الخالِصُ ۚ وَالَّذينَ اتَّخَذوا مِن دونِهِ أَولِياءَ ما نَعبُدُهُم إِلّا لِيُقَرِّبونا إِلَى اللَّهِ زُلفىٰ إِنَّ اللَّهَ يَحكُمُ بَينَهُم فى ما هُم فيهِ يَختَلِفونَ ۗ إِنَّ اللَّهَ لا يَهدى مَن هُوَ كٰذِبٌ كَفّارٌ

Absolutely, the religion shall be devoted to GOD alone. Those who set up idols beside Him say, "We idolize them only to bring us closer to GOD; for they are in a better position!" GOD will judge them regarding their disputes. GOD does not guide such liars, disbelievers.

[39:2] We sent down to you this scripture, truthfully; you shall worship GOD, devoting your religion to Him alone.

[39:4] If GOD wanted to have a son, He could have chosen whomever He willed from among His creations. Be He glorified; He is GOD, the One, the Supreme.
