I heard from somewhere, I don't remember. That if you talk bad about a jinn all the time they get mad and come beat you up or something. I was just wondering if I was the only person who heard that before. Did you?
Once my teacher told me a story about this guy that learned the name of a Jinn and kept saying it all the time mockingly because he didn’t believe that it would do anything and then one night he made a joke about it while sitting in his room and the Jinn opened his door, threw his head into the room and screamed. Apparently the man is now in a psych ward because he went cray cray after seeing that.
I don’t know how true any of that is but I wouldn’t take chances.
