In conservative Christianity, damnation is generally seen as reserved for those who don't not accept Jesus Christ as their Lord and Savior will go when they die, especially grown-ups who know about the bible, though in the strictest forms, it does not matter if you hear or how well you know the gospel. To others; it is generally seen as a place where spirits manifesting much evil go when they die. In Liberal christianity and Universalism; on the other hand; they generally reject the existance of Hell or damnation period.
In Islam; damnation follows a similar suit to Christianity. In conservative Islam; generally only a select few will not be damned or only those who accept Islam. Others reject damnation period, though universalism is far more rare in Islam.
