We did not send you (O prophet,) but to the entire mankind, as a bearer of good news and as a warner, but most people do not know.

They say, “ When will this promise (of the Day of Judgment) be fulfilled, if you are truthful?”

Say, “You hold an appointment for a day that you can neither put back for a while, nor can you put it forward.

Those who disbelieve say, “We will never believe in this Qur’ān, nor in that which was before it.” But if only you could see when the wrongdoers will be made to stand before their Lord, repulsing words (of blame) to one another! Those who were held as weak will say to the overbearing, “Had you not been there, we would have been believers.”

Those who were overbearing will say to those weak, “Had we stopped you from (accepting) guidance after it came to you? Rather, you yourselves were guilty.”

And those weak will say to those overbearing, “But (it was your) intriguing day and night (that stopped us from accepting guidance), when you were directing us to disbelieve in Allah and to set up rivals to Him.” And all of them will conceal (their) regrets when they will see the punishment. And We will place iron-collars around the necks of those who disbelieved. They will not be recompensed except for what they used to do.
