Is a son's dutifulness to his mother, despite not loving her, considered forbidden if she has wronged him, deprived him of his inheritance, and caused his wife and children to hate him?

If you are dutiful towards your mother and do not fall short in fulfilling her rights, then your lack of love for her does not harm you. However, do not surrender to feelings of hatred towards her. Instead, look at her good qualities and her right, which Allah has enjoined due to what she endured during pregnancy, childbirth, and upbringing.
