Divine Justice Demands a Day of Judgement
While describing the attributes of the Lord Almighty during the discussion of the Oneness of the Creator of the Universe, we have said that God is Just and so He has provided each and every essential thing for everything and every being, without being requested. A Persian couplet says :
We were inexistent and we never requested to come into existence. But the Mercy and Kindness of the Merciful Lord even hears our unsaid pleas.
One of the demands of God's justice is to give reward to those good people who, as we see, passed their whole lives in obedience, worship and piety but, in this world of ours, they got no reward in proportion with their labours and hardships. Likewise, the Just Lord's attribute of Justice also demands that He should punish offenders who, as we see, have indulged in various mischiefs and conspiracies and devastating corruption but no punishment is or has been given to them in this world. They pass away from this world continuing their offences and sins. Often it also happens that mischievous offenders live easy and luxurious lives whereas good people live in difficulties. We also see how much cruelty man shows towards man. They loot one another's property; kill one another and trample others' honour under their feet. Since God Almighty is Just, certainly a day will come when everyone will get his due based on his good or bad deeds. Right of everyone will be restored to him or her.
This day every soul shall be rewarded for what it has earned; no injustice (shall be done) this day; surely Allah is quick in reckoning. (40:17)
Those who had oppressed others will, surely be thrown into fire on that Day as warned:
Surely We have prepared for the iniquitous a fire, the curtains of which shall encompass them about ... (18:29)
The poor person who was unjustly killed will be able to take revenge from the evil oppressor.
And when the female infant buried alive is asked For what sin she was killed, (81:8-9)
And God may give reward/compensation to the oppressed victim. Good people may get rewards and evil ones may get chastisement so that His justice is manifested.
