What Is The Day Of Noise And Clamor?

The Day Of Noise And Clamor.
In the Name of Allah, Most Gracious, Most Merciful.
The (Day) of Noise and Clamor:
What is the (Day) of Noise and Clamor?
And what will explain to you what the (Day) of Noise and Clamor is?
(It is) a Day on which men will be like moths scattered about,
And the mountains will be like carded wool.
Then, he whose balance (of good deed) will be (found) light,
Will have his home in a (bottomless) Pit.
And what will explain to you what this is
(It is) a Fire blazing fiercely!   

On the Day when some faces will be (lit up with) white,
And some faces will be (in the gloom of) black: to those
Whose faces will be black, (will be said): 
"Did ye reject Faith after accepting it?
Taste them the Penalty for rejecting Faith."
[Surah Ali -Imran, 3:106]

Those who reject Faith-neither their possessions nor
Their (numerous) progeny will avail them aught
Against Allah:
They will be companions of the Fire-
Dwelling therein (forever).
[Surah Ali-'imran, 3:116]

Fear the Fire, which is prepared for those who reject Faith;
And obey Allah and the Messenger; 
That ye may obtain mercy.
[Surah Ali -Imran, 3:131-132]
