Daughters Accusing Their Father of Injustice: Should They Boycott Him, Especially If Their Mother Requests It?

Question:
Honorable Shaykh, may Allah grant you success. A group of daughters say that our father has married another woman besides our mother and that he is unjust to us. Is it permissible for us to boycott our father? Please note that he does not give us anything from the social security benefits, and our mother asks us to boycott him. What should we do? Should we boycott him?

Answer:
No, this is undutifulness to parents. Undutifulness to parents is not permissible, and you should not obey your mother in this, because undutifulness to a parent is a major sin among the major sins. Even if he treats you badly, you should treat him well. Fulfill what is your right and ask Allah for what is your right, and fulfill what is your duty and ask Allah for what is your right. As for you being undutiful to him, no, it is not permissible. Yes.
