Do you believe in black magic [Spirituality & Religion]

I have personally seen it work no joke . A guy once asked my name and my mothers name including date of birth and there right in front of me he told me my past and everything. And this is someone who I had never met in my life.

According to some religions every human is born with a jinn that is supposed to mislead them that jinn is with you from birth so he knows everything so when these people ask you date of births etc they communicate with your jinn through prayers and ask him about your life
