Quran 39:2 — The Throngs (Al-Zumar)

We sent down to you this scripture, truthfully; you shall worship GOD, devoting your religion to Him alone.

[39:1] This is a revelation of the scripture, from GOD, the Almighty, the Wise.

[39:3] 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.
