What is the ruling on a mother's anger towards her daughter if the daughter confronts her about her reprehensible actions, and does that affect Allah Almighty's pleasure?

Spying on one's mother is not permissible unless there is a justifiable reason, such as the appearance of suspicion. The mother's right is immense and does not diminish, no matter her condition. It is obligatory to honor her, even if she is disobedient. Among the greatest forms of honoring her is enjoining good upon her and forbidding evil, and preventing her from unlawful acts with gentleness and respect. You must strive to honor your mother, continuously advise her, and warn her of the consequences of speaking with young men. If she does not desist, inform someone who can prevent her. Her anger will not harm you; rather, you will be rewarded for it.
