If the case is as you have mentioned that you maintain kinship ties with your mother and sister by visiting them and sending them meat on occasions, you have done well. Perhaps, your mother and sister are looking forward to much goodness, such as inviting them to your house for the banquet instead of sending them part of it with your son. Indeed, they are more entitled to be invited to the banquet. They may (Part No. 25; Page No. 123) expect you go to them and give them the meat or whatsoever personally as a sort of showing gratitude and bringing happiness to them instead of sending your son. We advise you to be more dutiful
and kind to your mother and sister by inviting them to your house on `Eids and occasions as well as by visiting them. If they refuse to come to your house, you should go to them personally and give them the gift. If they refuse, as you mentioned because they do not like your wife, there would be no blame on you because you would have done your obligation. You are not required to divorce your wife to please anyone as long as your wife obeys Allah and fulfills her rights and duties and has not done any harm to your mother or sister.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
