The Ruling on Visiting Sorcerers and Magicians to Treat Sorcery

Question:
A brother of mine was ill for a period of time, a very long period, and I took him to many hospitals, but he did not benefit from any of it. After that, they said that he had some sorcery, so I took him to a person who claims to treat the disease of sorcery. He treated him by strange methods according to their specific and well-known methods, and he was healed by the permission of Allah. My question is: Am I sinful for that?

Answer:
Yes, if it is known that he practices sorcery, or claims knowledge of the unseen, then you are sinful. So you must repent to Allah, turn back to Him, and not return to him. But if he practices recitation, and permissible verses, not by sorcery, not by serving the devils, and not by claiming knowledge of the unseen; then there is no harm.
As for the one who is known to claim knowledge of the unseen, and says: So-and-so has afflicted you, and such and such has happened to you, on such and such a day, and you gave such and such on such and such a day, all of this is evidence that he serves the devils, or he lies, claiming knowledge of the unseen and lying, or serving the devils. This person is not to be visited, nor asked.
The Prophet (peace and blessings be upon him) said: Narrated by Muslim in the Sahih, and in the other wording: (peace and blessings be upon him), narrated by the people of the Sunan with a good chain.
And he also said - (peace and blessings be upon him): So it is not permissible for a Muslim to ask these people. The disease may be healed by many causes, and it may not be healed, so not every sick person is healed, and not every disease has a medicine that heals it. A medicine may be prescribed for him, but Allah has not decreed healing for him; because the wisdom is that the duration has ended, and the term has arrived, so medicines are conditional on the absence of the term, but if the term arrives, medicines do not benefit.
