And thy Lord shall cometh with angels, rank upon rank
And Hell, that Day, is brought (face to face); on that day man will remember, but how will the remembrance (then avail him)?
he will say: "Ah! Would that I had sent forth (good deeds) for (this) my (Future) Life!"
For, that day shall no one chastise with (anything like) His chastisement,
And none shall bind with (anything like) His binding.
The Holy Quran 089.021-026
Note: Although God encompasses everything and vision comprehend Him not... even then this very verse, that on the Day of Judgement: thy Lord shall cometh with angels, rank upon rank really brings an unimaginable vision. A vision that calls to fear our Almighty Lord who deserves the utmost reverence.
And also its worthy to remember the ancient wisdom of the Bible: The fear of the LORD is the beginning of knowledge. (Proverbs 1:7)
