Heaven and Hell are Eternal
[10:26] For the righteous, the reward will be multiplied manifold. Their faces will never experience any deprivation or shame. These are the dwellers of Paradise; they abide therein forever.
[10:27] As for those who earned sins, their requital is equivalent to their sin. Humiliation is their lot, and no one beside GOD can protect them. Their faces will seem overwhelmed by masses of dark night. They will be the dwellers of Hell; they abide therein forever.
Humiliation, shame, embarrassment are the worst feelings someone can have. When someone feels shame they have no dignity, authority or respect.
[6:160] Whoever does a righteous work receives the reward for ten, and the one who commits a sin is requited for only one. No one suffers the slightest injustice.
[88:1] Are you aware of the Overwhelming? [88:2] Faces on that day will be shamed
