A person complains about his father, who is over fifty, and who oppresses them with his words and actions, always suspecting and criticizing them. He incites the son against his mother and asks him to spy on her, and he alludes that the son is not his, and he accuses his wife of adultery without proof. He threatens divorce and wants to break up the family. The son asks if it is permissible for him to take his mother and siblings to live away from his father in a rented house to live in safety away from psychological pressures and accusations.

All praise is due to Allah, and prayers and peace be upon the Messenger of Allah, and upon his family and companions.

If your father is abusive and unjust, this does not negate his right to dutifulness and companionship with kindness. It is permissible for adult children to live separately from their father without this being considered disobedience. If the mother is content to stay with the father, it is not permissible to remove her from his home. However, if she is divorced or harmed by staying with him, it is permissible to house her away from him. Living separately does not permit cutting off or abandoning the father; rather, dutifulness to him and visiting him to an extent that does not cause harm are obligatory, along with gentle admonition and guidance towards goodness.
