What is the ruling on wearing items that are medically believed to be causes of healing?

Question:
The questioner says: There is a copper ring sold at the pharmacy that is worn on the hand. They claim that it relieves the pain found in rheumatoid bones. What is its ruling?

Answer:
If it is medically established that it has a medical benefit, there is no harm in it, there is no harm in it, because it is a form of treatment. If the doctors decide that the material from which the ring is made has a benefit for the patient, that it absorbs something from his body or from his skin, then there is nothing wrong with that, because this is among the permissible means.
Yes. However, if the ring has not been determined by doctors to be medically beneficial, but rather it is taken based on the belief that it cures the disease or prevents the disease from occurring, this is what is forbidden. When the Prophet (peace and blessings be upon him) saw a ring on a man, he said, "What is this?" He said, "It is for the weakness," meaning from the fever. He took it to protect himself from the fever. He said, "Remove it, for it will not increase you except in weakness. If you were to die while it is on you, you would never succeed." If one believes in it that it cures or that it prevents disease, and there is no basis for this in medicine, then this is a belief in superstition. Is it not permissible? Yes.
