What is the meaning of the qamarah used by sorcerers to cast spells on people?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the meaning of the qamarah that people use, or that sorcerers use, to cast spells on people?

Answer:
The qamarah is illusion. They make people see things as other than they are. They make it seem to him that he is striking himself with a knife, while he is lying; he did not strike himself, he is merely playing with the knife. They make it seem to the onlooker that he is striking himself. They make it seem to him that he is pulling a car with a hair, while he is a liar and is not pulling it. They make it seem that he is walking on nails. This is a lie.
The car does not walk on them; the car is above and the nails are below. The nails are far from the car, but through the jinn they make it seem to people that he is doing this, that he is walking on fire or swallowing a coal. All of this is a lie. If he were truthful, he would have a coal and open his mouth and throw the coal into it. If he were truthful, he would have a knife and stab it into it. All of this is a lie and deception. Yes.
