On The Day of Judgment, the reality of afterlife and the true religion Islam will become clear to everyone. Those who had
indulged in evil deeds and followed false beliefs will wish that they had never existed; but they will have to face the final justice.  May
God have mercy on all of us.
WHEN WILL THE DAY OF JUDGMENT ARRIVE?
Qur'an Chapter 33 Verse 63
Men ask you of the Hour,  Say the knowledge of it is with God only,
What can convey to you that may be the Hour is near.
Qur'an Chapter 29 Verse 53
They bid you to hasten on the doom.
And if a term had not been appointed, the doom would have definitely come on them.
And it will come upon them suddenly when they perceive not.
             Superficially, it seems that if we knew the rate at which the expansion of the universe is slowing, then we should be able to
predict when the Day of Judgment will begin. However, if time is related to the expansion of space, we cannot observe the slowing of
the expansion. This would be like attempting to measure the speed of a car with a clock that is connected to its wheels, so that the
speed of time would depend on the speed of the car. If the car slowed-down the time will also slowdown and speed of the car would
always appear the same. Similarly as the expansion of the universe slows time and motion will also slowdown, the rate of expansion,
will appear the same.
Qur'an Chapter 53 Verse 57-59
The threatened hour is near. None beside God can disclose it. Are you surprised then at this statement?
               Paradoxically the far-reaches of space may even seem to expand faster when measurements are made with our local
slowing time. The nature of time is such that slowing of time also cannot be perceived. This of course means that the beginning of
the Day of Judgment cannot be predicted and may come at any time. Only God, who is independent of time, knows of the real timing
of the Day of Judgment.  

                                                                       WAITING IN THE GRAVE FOR DAY OF JUDGMENT TO ARRIVE?

             In the Quran, the soul is compared to consciousness and death is compared to sleep. Once death overcomes us there is no
perception of the passage of time and the next thing we see will be the Day of Judgment.   
Qur'an Chapter 30 Verse 55-56
And on The Day when the Hour arrives the guilty will swear that they remained (dead) but for an hour,
thus they were ever deceived but to those to whom knowledge and faith are given will say:
”The truth is that you have remained (dead) until the Day of Resurrection by God's decree.
This is the Day of Resurrection, but you used not to know.”
Qur'an Chapter 45 Verse 27
To God belongs the Sovereignty of heavens and the earth and on the Day when the Hour rises,
those who followed falsehood will be lost.
