What is the philosophy behind the existence of the Day of Judgment?

One of the beliefs in Islam is the existence of the Day of Judgment. We want to see what is the philosophy behind being such a day?

There are three realms regarding the whole life of mankind, the first one is this material life, the life and the world in which we live, that the average lifetime of a human in this time is around seventy years.

There is a second world and life that is known as the realm of Barzakh or the world after the death and before the third world, and there will be the third world that starts after some happenings that are mentioned in the holy Quran and the Narrations, and this world is known as the day of judgment, a world that is the most complete realm.

Let me start the discussion with an example:

Imagine a murderer who has killed for example seventy humans without any lawful reason. He is brought to a court; the judge wants to have a just decree. In your idea, is it possible to punish such a murderer with a decree that the whole justice will be fulfilled or not? Can we kill this murderer more than once? So how does the justice of Allah can be manifested completely?

Another example, in many cases in this world the guilty person runs away or no court is held for such a person or through a wrong decree of a judge, the sinless people get punished instead, so how does the justice of Allah come true regarding these guilty individuals?

So we realize that this world because of its incomplete capacity cannot be a place for fulfilling the whole rights of the humans. From the other side, we have proved through intellectual argumentations that Allah is just, so there must be a world that is a complete world from every aspect and that is the realm of day of judgment.

 

The Day of Judgment is a day in which the actions of the people from the very beginning of the creation to the end, will be calculated and will be the causes for rewards or punishments. And the justice and appointments and promises of Allah, will be manifested for humankind.

The one who really believes in the day of judgment, he/she knows that in a day he/she will be responsible for his/her deeds, so he/she does not try to cheat people or do cruelty even though no one gets aware of that, but because he/she sees him/herself in the presence of Allah and in the presence of the angels who write the deeds of mankind, he/she does not lose the observation and self-control.

Another philosophy of this belief is that, believing in a world after this material world, gives meaning to the life, you might see in the west that many of those who do not believe in the worlds after death, after fulfilling their wishes or at the time of getting old, they get so much disappointed because they see themselves that are going to be perished because they look at the death as the last stage of the existence. But the one who knows that this material life compared to the next lives, is nothing, he/she always is hopeful and the tolerance of the problems is easier for him/her than those who do not have such beliefs.
