Islam
In Islam, there are two general stages after death: the minor Judgement (al-Qiyama al-Sughra) which begins for every individual the moment they die, and the major Judgement (al-Qiyamah al-Kubra) which is a set event for all the creation.
The minor Judgement, also referred to in the Quran as the barrier (Barzakh), is where all the souls remain inside the grave where they were buried waiting for Yawm ad-Din (the Day of Judgement). Every soul spends its time in the Barzakh in either pleasure or torment, and get a glimpse of its final destination through a window. Those who had many sins may face some punishment in the grave that would reduce or expiate their punishment on the Day of Judgement.
When the Day of Judgement begins, all creation is destroyed, then a new universe is created. All the creation will be resurrected in body and soul in their original form, naked and uncircumcised. The Throne of God (Allah is the Arabic word for God) will be brought forth onto the new earth, carried by eight enormous angels. God will call every person into Judgement individually, speak to them directly without a translator, and weigh their deeds on the scale. The paths after Judgement are two: the first is Jannah (Arabic for Gardens), roughly the equivalent of paradise, and the second is Jahannam, the equivalent to Hell. One's assignment to Jannah or Jahannam are determined by two things: their monotheistic belief in God without partners, and one's deeds in life. Those who believe in God and perform good deeds will be admitted into Jannah, whereas those who do not believe in God are punished in Jahannam eternally. Those who believe in God but had many sins will be sent to Jahannam until their sins are cleansed, then they are revived and admitted into Jannah.
Jannah is described in the Quran as a garden of perpetual bliss with rivers flowing underneath; it is bigger than the heavens and the earth of the current life. It is in the shape of a hill, with the center of it as the highest rank, where the Prophets will reside, right underneath the Throne of God, and where the springs of all the rivers of Jannah flow. The inhabitants live in a state of happiness and satisfaction with no worries or problems. The People of Jannah live in beautiful conditions in which they get everything they desire: beautiful spouses, clothes, servants, surroundings, food, etc.; all of the things indicative of a perfect life in the current world. In addition, they are brought close to God. Meanwhile, those in Jahannam are tortured, primarily by methods relating to scolding fire or freezing ice, for eternity, or until Allah wills for some of them to be saved.
The Quran explicitly states that Jannah is not an exclusive abode for followers of Muhammad. Rather, all monotheistic believers in God in all eras, such as Jews who followed Moses and the Christians who followed Jesus, will enter Jannah if they believed in God and did good deeds. Also, Muslims are not guaranteed Jannah. Rather they must be cautious not to die upon an act of polytheism that would lead them to the Hellfire eternally.
