According to the Quran only Allah Knows who will go to Jahannam (Hell) and who will go to Jannah (Paradise). Those who ignored, or only pretended to believe in Allah will remain in Jahannam after Qiyamah (Judgment Day).
Muslims believe that after facing the Judgment of Allah, they will be either admitted to Paradise by His Mercy, or entered into Hell by His justice.
Day of Judgment ( Qiyamah, قيامة ) is believed to be Allah’s final assessment of humanity as it exists. The sequence of events (according to the most commonly held belief) is the total destruction of all creatures allowable, resurrection of the body, and the judgment of all creatures.
The exact time when the events are to occur is not specified, however there are said to be major and minor signs which are to occur near the time of Qiyamah (End Time). In the Quran verses, especially the earlier parts are dominated by the idea of the nearing of the day of resurrection.
Muslims believe that the afterlife will be filled with happiness and peace for believers and those who do good deeds.
In Islam on Day of Judgment (Qiyamah), all living things will be raised to life again and called in front of Allah for the final judgment. People will be divided; some will enter Jannah (Paradise) and some will enter Jahannam (Hell-Fire).
The Quran describes this Day of one of happiness for the believers, and terror for those who disbelieved in its existence. The Quran emphasizes the power of God: “Surely, He who brings life to the dead earth through rainfall can surely give life to men who are dead” (Quran Fussilat, 41:39).
In Islam, True Muslims must believe in the day of Judgement as one of the six articles of Faith (Iman). The trials and difficulties associated with it are detailed in both the Quran and the Hadith.

Muslims believe that the Quran provides the framework for understanding the Day of Judgment such as Prophet Isa (Christians refer Him as Jesus) to Earth, the presence of a false prophet (the Dajjal) in the period leading to Qiyamah and the second kingdom before the occurrence are believed to be indirectly mentioned in the Quran.
There are a wide variety of understandings of the verses in the Quran referring to the Day of Judgment:
• The timing of the day of judgment is not known to people – onlyAllah knows when it will occur.
• The people will believe that a short time has passed betweentheir deaths and resurrection.
• Nothing will remain except Allah.
• Allah will resurrect people even if they turned to stone or iron.
• Angel Israfil will blow the Trumpet twice: the first time all
creatures will swoon and the second time the resurrection wilcome to pass. Allah said “First blow will bring the Universe toattention to all life and Second blow will end all life and Thirdblow will bring mankind back to life again (Judgement beforetheir Lord) (Quran Al Zumur, 39:68)
The Quran declares that the belief in Allah and the last Prophet Muhammad (including the belief in all the prophets of Islam) and the last Day of Judgment and the doing of good works on earth isthe requirement for salvation, provided that Shirk is notcommitted. Believing in and observing in the five pillars of Islam:Tawheed, Salat, Fasting, Zakat and Hajj are necessary to secureParadise.
No injustice shall be doneSurely Allah does not do injustice to the weight of an atom, and if it is a good deed He multiplies it and gives from Himself agreat reward. (Quran Al Nisa, 4:40)
• Non-Believers will go to hell
