In Hell, everyone will be repaid in full for what they did. Certainly people will be ranked according to the intensity of their disbelief, the confusion they stirred up concerning the believers and Allah's religion, and according to the seriousness of the wrongdoing they used to commit in the world. For example, it is declared in the Qur'an that hypocrites, the main enemies of believers against whom they hatch secret plans, will be in the lowest level of the Fire (Surat an-Nisa': 145). Likewise, it is stated in the verse below that all unbelievers will certainly enter the Fire and, with the justice of Allah, will be paid in full for what they did:
Those are people of whom the statement about the nations, both of jinn and men, who passed away before them, has also proved true; truly they were the lost. Everyone will be ranked according to what they did. We will pay them in full for their actions and they will not be wronged. (Surat al-Ahqaf: 18-19)
Beside s this, unless Allah wills otherwise, people will not be forgiven and released from Hell after a given period of punishment for their wrong actions. Every unbeliever who enters Hell will remain in it for eternity, forever (Surat al-Baqara: 80-81).
