text: do you think there is ghost in the world? why?   according to islam, djinn exist. they are not ghosts, but they're creatures living in another dimension.   those creatures have the good and the bad amongst them. they are used by magicians. muslims are warned not to resort to magic because it is evil. very few do, and those who do, do it through jinn.  according to islam, some jinn are muslims while some are non-believers.  i hope i answered your question.
