Where does the Koran describe the idolatrous religions?
* As for the idols they set up beside GOD, they do not create anything; they themselves were created. They are dead, not alive, and they have no idea how or when they will be resurrected. (16:20-21)
* Do those who disbelieve think that they can get away with setting up My servants as gods beside Me? We have prepared for the disbelievers Hell as an eternal abode. (18:102)
* They worship beside GOD idols that possess no power to harm them or benefit them, and they say, "These are our intercessors at GOD!" Say, "Are you informing GOD of something He does not know in the heavens or the earth?" Be He glorified. He is the Most High; far above needing partners. (10:18)
* Yet, they set up beside GOD idols from among the jinns, though He is the One who created them. They even attribute to Him sons and daughters, without any knowledge. Be He glorified. He is the Most High, far above their claims. (6:100)
* They even worship female gods besides Him; as a matter of fact, they only worship a rebellious devil. (4:117)
* Pagans indeed are those who say that GOD is the Messiah, son of Mary. The Messiah himself said, "O Children of Israel, you shall worship GOD; my Lord and your Lord." Anyone who sets up any idol beside GOD, GOD has forbidden Paradise for him, and his destiny is Hell. The wicked have no helpers. (5:72)
And so on.
