How to Deal with Sorcerers

Question:
My question is: There is a man from the state of Bahrain named Abu Dujannah, but his real name is Ali al-Mulla. He claims to treat patients. However, when I went to Dammam—because my father had promised on Thursday that he would treat my mother—he came to the house and treated my mother. I saw him and almost hit him, but I was afraid of my father; because he is a man who smokes and shaves his beard. I asked him why he smokes? He said: I must be calm when they come to me and show me where the diseases are. Then he asked, "What is your name?"—to the mother—so she said: So-and-so. He wrote down some numbers with him and said that so-and-so are the diseases. Some of his answers were correct, and some were wrong. He gave the mother some papers on which only the name of Allah is known at first, and the rest is unknown. He said: "You put this in the pillow, and you burn this as incense, and you drink this." But—by the grace of Allah—I frightened my mother, so I told her: "If you use this medicine, something will enter you through the window," and she did not use it. He told my father, this fortune-teller, that his wife would be cured on Thursday. In fact, he stole my father's grocery store on Thursday and took from it a sum of sixty thousand riyals. But I did not remain silent about this matter; rather, I reported it, and we wanted to arrest him, but he escaped from us. He comes to Dammam every Thursday, and he is in partnership with a Saudi man in the operation; because it is he who contacts him. Should I report this Saudi man, or should I remain silent? And by knowledge, what is the ruling on the one who believes in this man and uses the medicine?

Answer:
There is no doubt that this is one of the fortune-tellers, the soothsayers, and the corrupters in the land. Such a person is not accepted, and his methods are not used in treatment. Rather, this person must be arrested and disciplined as necessary, and imprisoned as he deserves; so that he is returned to his country—if he is from outside this country—after review, and after the Shari'ah is applied to him. The court must look into his case and summon witnesses who know him, so that the court rules against him with the discipline, imprisonment, and other penalties he deserves.
It is not permissible for the one who says: "Your name is so-and-so," or "Your father's name is so-and-so," or gives words whose meaning is unknown... and broken lines, or broken letters, or similar things from Shaytan that are not known. All of this is evidence that he is one of the soothsayers, the astrologers, the fortune-tellers, or the lying tricksters who confuse people.
And his saying that her illness will disappear on Thursday indicates his ignorance and misguidance, for the disappearance of illness is not known when it will disappear except by Allah (Glorified and Exalted is He).
The conclusion: Such people are liars and sinners. It is not permissible to allow them to continue. Rather, they are among the fortune-tellers, the liars, and the claimants of medicine. They lie and take things from the jinn and Shaytan, and they use them to assist in some of their falsehood to take the money of people by falsehood.
And you, the writer, must write to us the name of the Saudi man—and we will not reveal your name, if Allah wills—you write the name of the Saudi man, and do not reveal your name if you are afraid.
