Hell is the abode which Allah (swt) has prepared for those who do not believe in Him (swt), those who rebel against His (swt) laws and disbelieve in His Messengers. It is the punishment for His (swt) enemies, the prison for evildoers.

It is the ultimate humiliation and loss; there is nothing worse:

Our Lord! Verily, whom You admit to the Fire, indeed, You have disgraced him, and never will the Dhaalimoon [polytheists and wrongdoers] find any helpers(3:192)

Know they not that whoever opposes and shows hostility to Allah and His Messenger, certainly for him will be the fire of Hell to abide therein? That is extreme disgrace“. (9:63)

The losers are those who will lose themselves and their families on the Day of Resurrection. Verily, that will be a manifest loss!(39:15)

How could Hell be other than we have described when it is full of utterly indescribable torment, pain and grief? It is eternal and its inhabitants will remain there forever. Allah (swt) has condemned them and their place in the Fire:

Evil indeed it [Hell] is as an abode and as a place to dwell(25:66)

This is so! And for the Tagheen [transgressors] – will be an evil final return – Hell! Where they will burn, and worst [indeed] is that place to rest!(38:55-6)
