Many religions believe in life after death however each differs in what happens after death. Some believe that justice would be served to those who committed crimes which could not be sentenced on earth. If a war criminal like Adolf Hitler and Ariel Sharon who killed many thousands of people.
In the worldly life the most severe punishment that can exist is death. However a person can only be killed one time, what about the millions of lives that he took when he had power? How will justice be served for these people.
A serial rapist who raped many women, a jail sentence would not bring back the dignity and the restore the feelings of victims. A mark is made on the victims’ lives that is not easy to heal. How are these people to receive their sentences in a way that is just to them and to those whom they wronged?
That is from the point of justice, the bigger question remains. How is everyone from the beginning of time going to be resurrected? Will everyone be in the state they are in now? What will be their age? How about those who had terminal illnesses since they were young or were blind or had no limbs?
How would these people be resurrected? The men and women with Down Syndrome, what wrong did they do and in what state will they be resurrected (if they ever will be)?
Say, ” God causes you to live, then causes you to die; then He will assemble you for the Day of Resurrection, about which there is no doubt, but most of the people do not know.”
But those who disbelieve say, “The Hour will not come to us.” Say, “Yes, by my Lord, it will surely come to you. [ God is] the Knower of the unseen.” Not absent from Him is an atom’s weight within the heavens or within the earth or [what is] smaller than that or greater, except that it is in a clear register.
Does man think that We will not assemble his bones? Yes. [We are] Able [even] to proportion his fingertips. But man desires to continue in sin.
Indeed, We have produced the women of Paradise in a [new] creation. And made them virgins. Devoted [to their husbands] and of equal age.
And they used to say, “When we die and become dust and bones, are we indeed to be resurrected? And our forefathers [as well]?” Say, [O Muhammad], “Indeed, the former and the later peoples. Are to be gathered together for the appointment of a known Day.”
And the Prophet said
Hasan Basri says that an old woman came to Muhammad and made a request, O Messenger of God make Dua that God grants me entrance into Jannah.
He replied, O Mother, an old woman cannot enter Jannah. That woman started crying and began to leave. Muhammad then said, Say to the woman that one will not enter in a state of old age, but God will make all the women of Paradise young virgins. God Ta’ala says, Lo! We have created them a (new) creation and made them virgins, lovers, equal in age. (Surah Waaqi’ah, 35-37).
From the few verses here it is clear the end of days is imminent however when is a matter of time. Everyone that ever lived will be raised in their best form. And then they would be judged. The judgement now is everlasting for all that was done by humans when they were alive.
If someone killed thousands of people they will indeed pay dearly for that. For each and every of those thousand lives and the sufferings caused to their relatives. Indeed the hereafter has to exist to provide justice that was outstanding here on earth.
