Suddenly

Those will have lost who deny the meeting with Allah , until when the Hour [of resurrection] comes upon them unexpectedly, they will say, "Oh, [how great is] our regret over what we neglected concerning it," while they bear their burdens on their backs. Unquestionably, evil is that which they bear.

Then We exchanged in place of the bad [condition], good, until they increased [and prospered] and said, "Our fathers [also] were touched with hardship and ease." So We seized them suddenly while they did not perceive.

Then do they feel secure that there will not come to them an overwhelming [aspect] of the punishment of Allah or that the Hour will not come upon them suddenly while they do not perceive?

The Prophet said, "My Lord knows whatever is said throughout the heaven and earth, and He is the Hearing, the Knowing."

But those who disbelieve will not cease to be in doubt of it until the Hour comes upon them unexpectedly or there comes to them the punishment of a barren Day.

And it will come to them suddenly while they perceive [it] not.

And they urge you to hasten the punishment. And if not for [the decree of] a specified term, punishment would have reached them. But it will surely come to them suddenly while they perceive not.

And follow the best of what was revealed to you from your Lord before the punishment comes upon you suddenly while you do not perceive,

Are they waiting except for the Hour to come upon them suddenly while they perceive not?

Then do they await except that the Hour should come upon them unexpectedly? But already there have come [some of] its indications. Then what good to them, when it has come, will be their remembrance?
