Do God’s revelations through the holy books correlate with the justice He will ensure for all the people on the Day of Judgement?

 

Verses 104-108 of Chapter 3:

There should always be among you some people who invite to what is good and enjoin what is right and forbid what is wrong: They alone will attain true success. And do not be like those, who became divided into sects and got involved in differences of opinion even after receiving clear teachings. Those (who have caused divisions), shall suffer a terrible punishment on the Day, when the faces (of some) will be brightened with joy and those of others shall be blackened with gloom. (It will be said to those,) whose faces shall be blackened, "Did you adopt the way of disbelief after receiving Faith? Well, then taste the torment for showing gross ingratitude towards it." As regards those, whose faces will be brightened, they will enjoy Allah's mercy and abide therein for ever. These are Allah's Revelations, which We are reciting to you in all Truth, for Allah does not will to be unjust to the people of the world.
