Jinn are creatures like us, created by our Creator, Allah, who created every thing, but their world and situation, is not like us. They are not metaphysic but they are true existence in their own world. Jinn are not Satanic beings because we read in Quran about Jinns saying: There are among us that are righteous, and there are contrary, we are groups of different ways) Sura 72, Verse 11.
Jinns are unseen by us, because of our limitations, but there existing just like us in their own world. We are not responsible to go through details of Jinns world, on the contrary, we should avoid trying to get any help from Jinns because that will cause more hardships. ( Sura 72, Verse 6).
