I have heard about people who work with Jinns or have access to them and can find out everything about you. Is this possible and what does Islam say about this matter?
It is not permissible in Islam to do anything with the Jinn. Allah (SWT)
in the Holy Qur’an said : “And some people from humans used to seek
help from Jinn but Jinn did not add on them but more difficulties”(Sura 72, Verse 6). So we Muslims are not allowed to try to approach Jinn or seek their help. Allah (SWT) guided us how to deal with our difficult situations relying on His help with out any need for Jinn.
Their world is their own world and our world is different world
completely.
Wassalam.
