[2] A similar concept can be found in the Jewish narrative in which the wicked are punished by angels of destruction in an intermediary state between the resurrection of the dead and the individual death.
[6] Despite the non-existent or at max, the brief mentionings in the Quran, Islamic tradition discusses elaborately, almost in graphic detail, as to what exactly happens before, during and after death, based on certain hadithic narrations.
After burial, each person is interrogated in the grave by two angels, called Munkar and Nakir, appointed by God to question the dead in order to test their faith.
[7][8] In the life of Barzakh, the souls of the sinners and disbelievers are kept and punished in a place called Sijjin which is said to be located at the lowest level of the earth (traditionally hell, before the Day of resurrection or underworld).
[9] There is belief that the fire which represents the own bad deeds can already be seen during the Punishment of the Grave, and that the spiritual pain caused by this can lead to purification of the soul.
