The Believers - 23:117
And whoever worships another god besides Allah, who has no proof, his reckoning is with his Lord. Surely the disbelievers cannot succeed.
Originator/35:40
"Say, "Have you considered your partners whom you call besides Allah; show me what they have created in the earth?"Or do they have a partnership in the sky? Or have We given them a Book and they rely on a proof in it? Indeed, the wrong-doers give only deceitful promises to one another."
The Bee/16:20
Those whom they call upon besides Allah cannot create anything, but they themselves are created.
The Pilgrimage/22:73
People, here is an example for you that you may listen attentively: Those whom you serve beside Allah, even if they were gathered together, they could not create even a fly. Even if a fly snatches something from them, they cannot take it back from him. Both the one who asks and the one who is asked are powerless...
The Ants/27:62
Who responds to the call of the distressed, and removes evil and makes you heirs of the earth? Is there another god besides Allah? How little do you take admonition?
The Ants/27:63
Who guides you in the darkness of the land and the sea? Who sends the winds as good tidings before His Mercy? Is there another god besides Allah? Allah is far greater than those whom they associate partners.
The Ants/27:64
"Who is He who began the creation and then repeats it? Who sustains you from the sky and the earth? Is there another god besides Allah? Say, "Bring your proofs if you are truthful."
