Quran 39:3 — The Throngs (Al-Zumar)

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.
