Belief of afterlife in Islam
The concepts of resurrection, heaven and hell have been part of Islam since Mohammad. Both Qur'an and Hadiths refer to the afterlife. According to Islam, when a human dies, he remains in a sort of interworld which is called as barzakh until the day of resurrection. Upon death, both body and spirit die and spend a period in the grave where they undergo a personal judgment by two angels and a divine judge. The day of resurrection is believed to last thousands years.
On the day of resurrection, the souls rejoin with their bodies and are assigned eternal life either in heaven or in hell depending on their merits. Heaven is located at the macrocosmic center of light and it is composed of eight levels. It is said in Qur'an that heaven is a place where it stores all kinds of delights are for the saved ones. Outer part of the macrocosm has the hell arranged in seven layers where the soul is punished by burning in fire. It is stated in Qur'an that hell is a place of which its fuel is stone and soul.
