The Ruling on Treating Illness with Arab Medicine

The questioner: He also says that some people suffer from nervous disorders and paralysis, and that some people claim to have Arab medicine. First, they apply cauterization to the head, then confine the patient in a dark room for seven days on a diet without salt, and he is not to hear any sounds. Is this correct or not? Please inform us, may Allah guide you.
The answer: Most of medicine, or much of it, is based entirely on experiments. If an Arab or non-Arab doctor uses beneficial medicines that contain nothing forbidden by the Shari'ah, no treatment through shirk, and no treatment with impurities, but rather treats with permissible matters from permissible medicines, such as cauterization or permissible recitation, all of this is permissible. This is because medicine varies and diversifies, so it is not a condition that it be imported from Europe or America or elsewhere. Rather, whenever there are texts indicating its benefit, it is acted upon, and whenever something is tried, such as pills, fruits, cauterization, or otherwise, for certain diseases, there is no harm in it.
The conclusion is that the majority of medicine, or much of it, is nothing but experiments. If a person who practices medicine tries a treatment by cauterization for some diseases, or a diet for some diseases, or places the patient in a room with no light because it benefits him in some diseases, or protects him from salt or such and such, all of this is permissible according to the experiments, on the condition that there is nothing in this that contradicts the command of Allah (Mighty and Majestic). These procedures must not contradict the Shari'ah.
As for treatment with something that contradicts the Shari'ah from the known prohibitions, it is not permissible. This is because the Messenger (peace be upon him) said: And it was narrated from him (peace be upon him) that he said: And when some people asked him about making khamr (intoxicants) for medicine, he (may Allah's prayers and blessings be upon him) said: So he (may Allah's prayers and blessings be upon him) made it clear that khamr (intoxicants) is not a medicine, but rather a disease.
So the conclusion from this is that the thing that has been tried and known to be beneficial, whether it is cauterization, a fruit that is eaten, pills that are eaten, an ointment, a diet avoiding other things, or the like of that which does not contradict the Shari'ah, all of this is permissible, and praise be to Allah: This is a known matter, and Allah (Mighty and Majestic) made Thus the hadith came, saying (may Allah's prayers and blessings be upon him): Yes.
