Qur'an 20170902
27. Say, "Show me those who you have joined with God as partners... by no means! No, God is Allah, the Exalted in Power, the Wise."
28. We have not sent you but as a messenger to men, giving them glad tidings, and warning them, but most men understand not.
29. They say,"When is this promise, if you are telling the truth?"
30. Say, "The appointment to you is for a Day, which you cannot put back for an hour, nor put forward."
31. The unbelievers say, "We shall neither believe in this scripture nor in that before it." Could you but see when the wrongdoers will be made to stand before their Lord, throwing back the word on one another! Those who had been despised will say to the arrogant ones, "Had it not been for you, we should certainly have been believers!"
