Is it considered disobedience for a son to point out to his mother the mistakes she made under the influence of others, and would he be sinful if his mother died angry with him based on false accusations?

One must treat parents with kindness and avoid displeasing them, and communication with them should be gracious. It is permissible to repel injustice and transgression from them, while maintaining their dutifulness and avoiding ill manners. One should delay a response if it leads to conflict. The mother must not abuse her right to her child's dutifulness in a way that harms him, and the child must increase patience with his mother and siblings.
