Ruling on a doctor treating a woman in the presence of a secretary?

The questioner : He says, a woman comes to see the doctor, meaning she is a patient, so it is necessary that there be no seclusion, so this one enters with the patient?

The Shaykh : It is necessary, what?

The questioner : The secretary must be present to negate the seclusion.

The Shaykh : This reminds me that this treatment follows the school of one of the schools that is not among the four, nor among the forty! It is the school of Abu Nuwas. What did he say? "And cure me with that which was the disease." And cure me with that which was the disease.
Be patient, everyone, it shows that the group is thirsty. Listen, my brother, we are not finished yet. Any Muslim doctor who hears the previous statement and believes in it—I say believes in it, because it is not enough to know it; knowledge is one thing and faith is another, and these are two matters. I believe it is obligatory for every Muslim to distinguish between them. Knowledge is one thing and faith is another. Knowledge may be shared with, accompanied by, and deceived by disbelief, whereas faith is that which distinguishes itself from disbelief. Therefore, it is not enough for the Muslim to know, and by Allah, this is a true statement, but he must believe in it so that his faith becomes a motivator and a deterrent for him to act upon what he has learned and what he has believed in. It is not permissible for the Muslim doctor to treat women. We always advise our brother doctors that they must strive and intentionally avoid, as much as they can find a way to do so, treating women. We say, "Necessities permit the prohibited." This is not hidden from a student of knowledge: "Necessities permit the prohibited." But this does not mean it becomes a system where this doctor does not distinguish between treating a man or treating a woman. He must block the door to his treatment of women except in necessity. And I know from experience that when these Muslim doctors open the door to treating women, the treatment becomes continuous, with no difference between his treatment of a man or his treatment of a woman. In fact, the situation may completely reverse, and the doctor becomes a specialist in treating women's diseases. And here lies the trial, and here comes the previous question. The answer, in truth, is as they say, and no blame, for religion is advice: this is an excuse worse than a sin, to say, "I do not even seclude myself with the sick woman, so I am forced to have a secretary with whom I seclude myself, even if there is no patient." Glory be to Allah. True is the one who said that this is the school of Abu Nuwas: "And cure me with that which was the disease."

The questioner : The last one says that he has a secretary who is his sister.

The Shaykh : The answer has already been given, may Allah reward you. But this is a mahram, and this is a type of permissible treatment. I said the answer has already been given that it is not permissible to take a secretary who is not a mahram to him. And this is his sister, so this is a type of treatment.

The questioner : Some claim that by doing this, he has good intentions and that his heart is pure.

The Shaykh : The answer has already been given.
