Yaseen - 36:23
Shall I take gods besides Him? If the Most Merciful wishes to harm me, their intercession can neither benefit me nor save me.
On that Day no one will be able to intercede for anyone:
The Cattle/6:94
You have come to Us as one, just as We first created you. You have left behind what we made you imagine. We do not see your intercessors with you, whom you claim to be partners (with God in the decision to be made about you). The ties between you have been severed. Those whom you used to put forward have forsaken you.
The Heights/7:53
"Are they waiting for the fulfillment of its news? On the Day when its news is realized, those who disregarded it before will say: "The messengers of our Lord brought the truth. Is there an intercessor for us? Or that we may be sent back to behave differently from what we did before."They have lost their identity and what they fabricated has deserted them."
Prophet Jonah/10:18
"They leave Allah and serve those who can do them neither harm nor good, and say: "These will intercede for us with Allah". Say: "Do you inform Him of what Allah does not know in the heavens and the earth? He is Most High, far from what you associate partners with."
The Cow/2:48
Beware of a Day when no one will be able to pay for anyone, no intercession will be accepted, no ransom will be taken from anyone and no help will be given.
The Cattle/6:70
Leave those who take their religion as a pastime and are deceived by the life of this world. Remind them with this (the Qur´an) so that a person may not suffer the disastrous consequences of what he has earned. He has no Owner and intercessor except Allah. Even if he gives any ransom, it will not be accepted from him. These are the ones who suffer the disastrous consequences of what they have earned; they deserve a drink of boiling water and a painful torment because of their disbelief.
The Romans/30:12
On the Day when the Hour is realized, the criminals will be shocked.
The Romans/30:13
And none of their partners whom they used to associate will intercede for them; they will disbelieve in their partners.
The Prostration/32:4
It is Allah Who created the heavens and the earth and all that is between them in six days and then established all authority. There is for you no guardian (owner) or intercessor (intermediary) apart from Him. Do you not understand the admonition?
The Companies/39:43
"Have they taken intercessors besides Allah? Say, "Even if they have nothing and cannot think"?"
The Companies/39:44
"Say, "To Allah belongs all intercession."To Him belongs the government of the heavens and the earth. Then to Him you will be returned."
The Forgiver/40:18
Warn them of the Day that is coming, then their hearts will be in their throats and they will swallow. For the wrongdoers there will be neither a friend nor an intercessor.
