In pre-Islamic Arab tradition, belief was based on fear of spirits and demons, called "Jinn" in Arabic. In traditional Arab legends, such as “Sinbad” and “Aladdin” from the stories of One Thousand and One Nights, jinns appear.
According to belief, another world exists parallel to the physical world, which is the kingdom of demons (Aljinn). The father of the jinn is Iblis, who caused Adam and Eve to be tempted and eat from the forbidden tree.
Like humans, demons also have kings, princes, tribes, and religions. They are mentioned in many places in the Quran. They appear as a gift that God gives to King Solomon in the form of control over the kingdom of demons.
Ghuul is a general name for demons and monsters in Arab culture.
