The Miraculous Qur'an answers all questions and objections.
21:22 If there were other gods besides God, there would have been chaos in both, the heavens and earth. Glorified is God, the Lord of Supreme Control, above all that they contrive. [3:84, 6:3, 16:51, 39:67]
17:42 Say, "If there were any other deities side by side with Him, as they claim, even those would have to find a way to the Lord of the Throne of Almightiness.”
17:43 Glorified is He, and High Exalted above what they say!
