What is your opinion on the issue of seclusion, such as a driver being alone with a woman, and others like it?

Question:
Your Eminence the Shaykh! The questioner says: Among the matters in which people are lax is the issue of seclusion, and among its forms is a driver being alone with a woman, a doctor being alone with a patient, and the reverse. Do you have a word on that, may Allah preserve you?

Answer:
A man being alone with a woman is not permissible by the consensus of the Muslims. A man being alone with a woman is not permissible, even if he is her mahram (a relative one may not marry); it is not permissible by the consensus of the Muslims, whether he is a doctor, a driver, her husband's brother, her cousin, a neighbor, or otherwise. It is necessary that there be no more than that; it is necessary that he be trusted and that there be no suspicion. This is based on the saying of the Prophet (peace and blessings be upon him): "No man is to be alone with a woman except with..."
...in the two Sahihs (authentic collections), the prohibition of that as well. A man being alone with a woman who is not his mahram is not permissible; there must be that, or more, so that the suspicion is removed. So it is not permissible for a woman to be with her husband's brother alone, or with the driver alone, or with her cousin alone, or with the neighbor alone. No, no, not in a car and not in a sitting room, where the two of them are together. Satan is eager; he may sow discord between them, as he said (peace and blessings be upon him) ... for Satan does not increase, he may sow discord and increase. So it is obligatory to be cautious. If a doctor wants to treat her, her mahram must be with her, her husband or her mahram or a woman with her, so that the doctor is not alone with her. Yes.
