Coming from an Arabic, Middle Eastern, country, I can write you down pages and pages about Jinn, and stories that many told over generations.
Yes, they have religions and live in tribes. They also worship God (at least some of them does).
They were made invisible to us as we cannot see them with our own eyes years ago. Before that they used to live in a parallel world to ours, without even a veil, as they promised not to interfere with Humans. That until Jinniyat (or daughters of Jinn) started to fall in love with Human males. Which they took as wives and ended up cursed that the veil was raised.
My grandmother once told me about a Priest that was abducted by the Jinn, and was asked to marry them in the forest of the village. He asked to take his ceremonial clothes, which he burnt with a cigarette in order to make sure he’s not dreaming.
He wakes up the next day and opens the closet. Which he found his clothes burnt at the same place he did. (excuse my English, I’m translating the story from Arabic - my mother tongue)
Several similar stories about abductions or Jinn taking humans in the night are always told by old-town folks. They also say if you made a pact correctly, they will grant you any wish you want. They can choose to work with you and call upon you even before you were born.
They act like you shadow, and can either be loving or unleash hell on you.
Any Sheikh or leader in a Muslim community or organization tend to keep a Jinn that helps him in his deeds and bindings, exorcisms, rituals…etc.
They also use them to either cause or break a curse, remove an evil eye effect, help a girl get married or cause her to be unlucky in Love.
There most effect as I’ve noticed was in the matters of Love, Luck in Love and marriage, and Money. They cannot help in healing nor serve properly in such contexts.
They’re mostly Arab Spirits Who Can Eat, Sleep, Have Sex, and communicate.
They are mortal and can reciprocate.
According to El-Zein, pagan Arabs (big believers in the occult) worshipped jinn long before Islam was introduced in the seventh century, believing that the spirits were masters of certain crafts and elements of nature who had the power to turn plots of land fertile. Jinn are believed to both interact with humans in our reality and lead their own lives in a separate realm. “As spiritual entities, the jinn are considered dual dimensional, with the ability to live and operate in both manifest and invisible domains,” El-Zein writes.
Hope this can help somehow.
