What Does Jahannam Mean?
Jahanam refers to the eternal abode of Hell, the afterlife place of punishment for evildoers. The punishments in Hell are carried out in accordance with the degree of evil one has done during this life.
Suffering in hell is both physical and spiritual, and varies according to the sins of the condemned. Hell in great detail in both the Qur'an and in the narrations of Prophet Muhammad (peace be upon him). For example, Hell has many levels (each one more severe than the one above it), each for a specific group of sinners.
