Is it considered an act of disobedience (ʿUqūq) to prevent one's daughter from going alone to her grandparents' house, and to allow her to go only in the company of her parents, in order to spare her from hearing music and learning some bad habits, knowing that the grandmother is angry and considers this behavior a lack of trust in her and an act of extremism?

A father has the right to prevent his daughter from anything that leads to corruption, because she is a trust under his care and he is responsible for her protection. Obedience to parents is not absolute; rather, it is restricted to what is righteous. It is recommended to be keen on honoring one's parents and to clarify the truth to them with wisdom and good counsel.
