The real inhabitants of Hell are those who reject God [I Am Enjoying Being A Muslim]

... they will remain in it forever, and shall never live in it or die.

However, there shall be another group of people who believed in God, the fire of Hell will touch them because of their sins, and they shall die a type of death until they become burnt up, then they will be interceded for, so they will come in groups and they will be thrown into The River Of Life, they will be refreshed, then it will be said, 'O people of Paradise, go ahead and enter it', so they will enter it.

Hell will never touch those who [u]repent[/u] from their sins.
