Do they await except its result? The Day its result comes, those who had ignored it before will say, "The messengers of our Lord had come with the truth, so are there [now] any intercessors to intercede for us or could we be sent back to do other than what we used to do?" They will have lost themselves, and lost from them is what they used to invent.

They are waiting for nothing but its final result (i.e. the punishment promised in the Qur’ān). The day when its final result will come, those who had ignored it earlier will say, “Surely, the messengers of our Lord had come with truth. So, are there any intercessors for us who could intercede in our favor? Or, could we be sent back, so that we might do contrary to what we used to do?” Indeed, they have put their selves to loss, and vanished from them all that they used to fabricate.
