What is my religious duty towards my mother who accuses me, mistreats me, and invokes evil upon me, despite my attempts to please her, and how should I deal with her in pursuit of Allah's pleasure and Paradise?

May Allah reward you for your kindness to your mother, your good treatment of her, and your patience with her. The Prophet, peace and blessings be upon him, said to a man who came to him seeking permission to go for jihad: "Stay with your mother's foot, for there is Paradise." We advise you to take steps to mend relations between you and her, such as: drawing closer to her, serving her, offering gifts, avoiding confrontation with her when she is angry, and making frequent supplications. You should gently advise her that cursing Muslims and supplicating against children are forbidden by Islamic law. If she does not respond, then be patient, for you will have a great reward. Remind your siblings to be patient and warn them against disobedience to parents.
