Surah 56. Al-Waqia, Ayah 3

 Unlike this world of sheer injustice, the Hereafter will put everyone in their right place. The righteous will be elevated in Paradise, while the wicked will be humiliated in Hell.

There will be a sorting out of Good and Evil. Or rather, (verse 7 below), there will be three main classes. Among the Good there will be the specially exalted class, those nearest to Allah (muqarrabun, lvi. 11-26), and the righteous people generally, called the Companions of the Right Hand (Ashab-ul-maimana, lvi. 27-40). And there will be those in agony, the Companions of the Left Hand (Ashab-ul-mash-ama, lvi. 41-56). Many who were high and mighty in this life will be brought low for their sins, and many who were lowly but virtuous will be exalted to various ranks and degrees. The old landmarks will be lost in the inner world, as they will be in the outer world.
