You may correct me if I’m wrong, but I believe that in Islam, Jinn are people who were made of smoke, the way that humans are created from dirt. They do have some magical ability beyond what humans do, but they also live in their own, sort of parallel world. There are good ones and bad ones, as they vary about as much as humans. And yeah if I’m not mistaken Satan is one of them, though I could be wrong about that.
