Arjay that is interesting about Jinns dying.
I knew a couple were living away from each other due to the Husband’s work. The Husband was missing his wife but most of all he was relentlessly worrying about her safety all the time. He couldn’t sleep or concentrate on work. He was always alone working and missed general company of other workers. The wife was living in an isolated place all alone and a lot of things would happen in that area yet the wife was never affected.
The Husband was extremely religious and a jinn walked into his office and told him not to worry and that he would guard his wife's house while the Husband was away. The Jinn was not allowed to go into the wife's home or see her, and if the wife would step out for a walk, the jinn would face away and know when she would go back inside. Once he walked into the Husband’s office and told him to reach home quickly and take his wife to the main city. Something serious did happen but the Husband reached just in time. Then one day that Jinn died. But a new Jinn soon came to the Husband afterwards.
So that was a good jinn that I heard about. :)
