You can inflict the evil on someone without even intending or knowing!
Watch this to understand what should be said : https://www.youtube.com/watch?v=yywMWuDZNlY

If a person admires someone or a trait of someone and has no intention of inflicting evil upon them, then is there anyway for there to be an evil eye? Can someone cause another to suffer from the evil eye if he has not intended to?

Is it possible that jinns seize people on their own or do people through practises call them upon certain people and control them? I have often heard such and such person had jinn in him so we took him to a person who can speak to the jinn and through some way can relieve the person of the jinn. I don’t know about all this so asking.
