جن‌ها (Spirits) are supernatural beings in various cultures, particularly in Islamic tradition. They are believed to be created from smokeless fire and possess free will, allowing them to choose between good and evil. جن‌ها can be invisible and are often thought to interact with humans in various ways, sometimes influencing thoughts and actions. In folklore, جن‌ها are often depicted as mischievous or malevolent, but they can also be benevolent. They are mentioned in the Quran, where they are described as living in a parallel world to humans. Some cultures also associate جن‌ها with specific places, such as haunted locations or desert areas.
