What is the right of a mother who commits forbidden acts, such as dealing in usury, has caused a severance of kinship ties, seeks to marry off her son to a Christian woman without her converting to Islam, and is preparing for divorce through deception, knowing that obeying her will anger the father and Allah? How can she be honored without disobeying Allah?

Thank you for your eagerness to honor your parents. It is your duty to avoid your mother's displeasure to the best of your ability, provided that doing so does not lead to committing something forbidden or exposing yourself to religious temptation. If visiting her leads to the presence of this girl or other temptations and sins, then it is sufficient for you to contact her by phone and fulfill her needs remotely.
