The Ruling on Going to an Unknown Person for Treatment

Question:
A well-known issue from some time ago: people take their sick person to a man for treatment, and when this man died, the illness returned to the patient.

Answer:
They are the ones who are at fault. They go to this man without knowing him, without knowing who he is, without knowing his creed, and without knowing anything else. This is negligence and a lapse in duty, and this is the true illness, the weakness, and the trial. This causes people to suffer from illnesses they did not expect. If they had relied upon Allah and taken the beneficial means, Allah would have made them independent of the forbidden and of the prohibited means. So one should not go to just anyone, nor to anyone who claims to treat, until one knows his trustworthiness and his standing, and knows his creed. Not just anyone who comes from here or there, or from the Shaytan, or from the jinn, or from any country, we make him a doctor, we make him a Shaykh, we make him a healer, and we go to him for treatment.
We do not know him, we do not know his creed, we do not know his religion, and we do not know the trustworthiness in him. This is part of the trial and the test. Yes.
