A Sister's Travel with a Driver, Her Seclusion with Him, and the Brother's Obligation

Question:
He says: Honorable Shaykh, may Allah grant you success. The questioner says: My sister goes with the driver to her distant job, and they are alone together, and my father permits her to do this. What is obligatory for me, given that my father says you have no concern with her?

Answer:
It is obligatory for you to report this matter to the men of the Hisbah (public authority) so that they may take action against the father, or to the court. It is not permissible for you to remain silent about this, because this is a clear evil. It is a manifest evil because she travels with him and is in seclusion with him. That means there are two dangers: the danger of traveling without a mahram and the danger of seclusion with a man who is not a mahram for her. But this man wants the money; he wants the money and does not care. There is no power and no strength except with Allah. So you must report that whoever takes action against him—either the judge or the head of the committee—should summon him, reprimand him, and take a pledge from him.
