Jinns are the spirit world, with some able to materialise. The devils are Jinn that mess with humans. The decent Jinn hide from us and never interfere with us. Some Jinn are Muslim, some Jewish (from the time of Solomon). Even though many Jinn now worship God, all Jinn alive today are said to be descended from Satan but originally Satan was just one of the Jinn himself, not the original one. He was very powerful and became captain of the angels but he wasn't one himself. He used to be very pious, in fact l read one legend that there was nowhere on earth where he did not prostrate in prayer to Allah. I guess Satan got so powerful that he decided God was just pretending to be infinite and could be overthrown, l guess God gave him a lot of power to continue the illusion for a set term before bringing him to justice. Btw ghosts are evil Jinn if they reveal themselves to us. Often they will be the accompanying Jinn that each human has, wandering the earth after the human's death, knowing the human's life intimately, hence mediums get their knowledge. I guess this more likely happens if the death was horrible. Bhaktajan, if you aren't Muslim (?) please say so otherwise it may confuse the topic (by the way l re-read your last post and found it very interesting and agreeable, though l don't know the truth of the matter).
