Can People Comeback From Hell After Entering Hell
We cannot fully comprehend how every blessing in Jannah will manifest. What we do know is the principle that whatever we receive will perfectly satisfy us and correspond to our deeds. Even the lowest level of Jannah is still Jannah, complete with its own beauty, comforts, and rewards. A person who reaches that level, especially after enduring hardship (of Hell, to whatever extent), will feel so profoundly blessed that they will not desire what they have not earned. Those who enter Jannah will possess a purity of heart that prevents them from making trivial or inappropriate wishes. The time to aspire and strive for higher ranks in Jannah is in this world, not in the hereafter.
