What should I do, as my mother has turned against me after my marriage, becoming displeased with me, and everything I do or say does not please her, despite my obedience to her, my fulfilling all her commands, and my wife's obedience to her?

A mother's strange behavior towards her son does not negate her right to dutifulness, and the fundamental principle in her case is compassion. One must strive to investigate the reason for the change in her treatment and eliminate the causes of her anger, and supplicate for her righteousness and guidance.
