The Cattle - 6:158 "Do they wait for the angels to come to them or for their Lord, or for some signs of their Lord? On the Day when some signs of your Lord come, they will not benefit him who has not believed before, or who has not gained any good in his faith. Say: "Wait, and we are waiting."
When Allah and the angels came, everything would end:
The Cow/2:210 Are they waiting for Allah and the angels to come to them from the dense clouds? Then everything would be over and everything would be returned to Allah.

The Dawn/89:21 Indeed, when the earth is shattered,
The Dawn/89:22 When your Lord comes with a host of angels,
The Dawn/89:23 On that Day Hell will also be brought. On that Day man will understand. Then what is the use of understanding for him!

The Cattle/6:8 "They say, "Should not an angel have been sent down to him!"If We had sent down an angel, the work would have been finished. They would not have been given time."

The Rocky Tract/15:8 We do not send the angels except for a definite purpose, and then no one is given a deadline.

The Criterion/25:25 The Day when the heavens will break up in clouds and the angels will be sent down in multitudes,
The Criterion/25:26 On that Day the dominion will belong to the Most Merciful, absolutely and completely. It will be a hard day for the disbelievers.

The Sure Truth/69:16 The sky is split, torn asunder.
The Sure Truth/69:17 Angels are on every side. On that Day your Lord will rule over the eight (universe).
