Its excruciating pain and horror described in the Qu'ran often parallels the pleasure and delights of paradise ( Jannah).
Punishment and suffering in Hell, in mainstream Islam, is physical, psychological and spiritual, and varies according to the sins of the condemned person.
The importance of Hell in Islamic doctrine is that it is an essential element of the Day of Judgment, which is one of the six articles of faith (belief in God, angels, books, prophets, the Day of Resurrection and providence) 'by which the Muslim faith is traditionally defined.' Simultaneously, jahannam is a term specifically for the uppermost layer of hell. It is often called by the proper name Jahannam. This notion is an integral part of Islamic theology, and has occupied an important place in the Muslim belief. In Islam, Jahannam is the place of punishment for unbelievers and evildoers in the afterlife, or hell.
