Knowing a sorcerer

Q 2: How can we recognize a sorcerer?

A: A sorcerer is a person who ties knots and blows into them or makes polytheistic incantations that contain names of some devils and Jinn and statements which are not understandable. He separates between a husband and wife and may kill the person affected by his spells. Every Muslim should avoid such people, warn people against them, and take their case to the authorities.May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
