supernatural being

Supernatural beings, also called Ghosts, Invisible Beings, or Astral Beings is the term used to refer to living beings whose existence can not be reached by the human senses. The word creature comes from the Arabic word meaning "created" and "Unseen" which means "invisible". So ghaib here means is when viewed from the point of view (senses) Humans against these creatures

Islam
In Islamic creed the term ghaib includes many things such as death, fortune, soul mate, human spirit, doomsday, heaven, etc. Believing in the unseen is one of the cautious Muslim characteristics. [2] Included into the unseen is a creature (creation) that can not be reached human senses such as from the angels and Jin. [3]

In Islamic beliefs revealed the existence of these unseen creatures, even before the first humans were created, the creatures of the genie had first inhabited the earth. However, due to his destructive deeds, most of the Jin's group was destroyed by Angels with the Devil (who was also from Jin's group [4]). Then Allah created man to be the Caliph of the earth, which later on Man and Jin lived side by side on earth with animals, plants, and things.
