Translation:

66. Do they only wait for the Hour that it should come on them all of a sudden while they perceive not?

Notes (Tafseer)

4665. Cf. xii. 107. What is there to wait for? The Hour of Judgment may come at any moment. It will come all of a sudden before they realise that it is on them. They should make up their minds to give up misleading disputations and come to the Straight Path.
