Do the legal responsibilities of the parents towards their two daughters (one unmarried and the other a widow, both living with them) cease due to their age and their rejection of parental authority? And what should they do about their Sharia-violating actions and their isolation, knowing that the parents are devout and keen on applying Islamic law?

An unmarried daughter residing in her father's home is under his responsibility. He is her guardian, and it is his duty to look after her religious and worldly affairs, discipline her, restrain her from corruption, and enjoin her to obey Allah. He has the right to prevent her from certain actions and to confine her if she commits acts that violate Islamic law. If daughters live separately from their parents without causing them sadness, or if they do not assist them because the parents are not in need, then there is no sin upon them. However, it is appropriate to sit with them and keep them company. The father retains the right to enjoin good and forbid evil even after his children are no longer directly under his guardianship. Parents should pray for their children's guidance and be a good example for them.
