وَكُلَّ شَىْءٍ أَحْصَيْنَـهُ كِتَـباً - فَذُوقُواْ فَلَن نَّزِيدَكُمْ إِلاَّ عَذَاباً
17. Verily, the Day of Decision is a fixed time, 18. The Day when the Trumpet will be blown, and you shall come forth in crowds. 19. And the heaven shall be opened, and it will become as gates. 20. And the mountains shall be moved away from their places and they will be as if they were a mirage. 21. Truly, Hell is a place of ambush 22. A dwelling place for the Taghun, 23. They will abide therein Ahqab. 24. Nothing cool shall they taste therein, nor any drink. 25. Except Hamim, and Ghassaq 26. An exact recompense (according to their evil crimes). 27. For verily, they used not to look for a reckoning. 28. But they denied Our Ayat Kidhdhaba. 29. And all things We have recorded in a Book. 30. So taste you. No increase shall We give you, except in torment. Allah says about the Day of Decision -- and it is the Day of Judgement -- that it is at a fixed time, with a set appointment. Its time cannot be added to or decreased. No one knows its exact time except Allah. This is as Allah says,
