Is the daughter considered sinful for telling her mother "May Allah not forgive you" after the mother hit her, and what should she do in this situation?

Cursing one's mother contradicts the command to be kind and speak graciously to her, as Allah Almighty has ordered: "And your Lord has decreed that you shall not worship except Him, and to parents, good treatment..." Therefore, saying "May Allah not forgive you" incurs great sin, and one must repent, seek forgiveness, and try to appease her. As for a mother severely beating her daughter, this is not permissible in Islamic law, and the daughter's disobedience does not justify this action.
