yes its wrong to consult Black Majicians and we should avoid. We should pray to God that none of us face this type of painful condition.
Very pious men are write Taveez with Zafran which just vanish when we put some water on it. This is not necessary that a common person just read the Quran and kill the evil. This is also a knowledge and from a proper way you can do it.
Anyway, just for a note, i’m not a person who visit Mazar and bow infront of the Grave of persons but for ta’veez i still believe they are no bad.
