The Ruling on Divorce During Anger

This is a letter received from Jibril Halim Muhammad from Qena Governorate in the Arab Republic of Egypt. He says: I live in a house that is beyond my financial means, and my mother is with me after her divorce from a man other than my father, and my wife is with me. However, there is discord and disagreement between my mother and my wife. I have reconciled them several times, and I have become angry with my wife in order to please my mother. During my anger, I say to her: "You are divorced." She then goes to her father's house, and when I appease her, I bring her back through the shaykh for the purpose of releasing the oath. Please note that my mother is sometimes the one who is wrong, and the second time as well, and the third time the shaykh told me: She cannot be taken back until you pay her a new mahr and we recite the Sunnah, and we did that. After that, a disagreement occurred again, so I expelled my mother from the house, and she stayed with my maternal uncles. Do I have a sin upon me because my mother is still angry with me? And what is the ruling on the divorce that occurred from me and the shaykh's words? Please inform us, may Allah reward you with good?
Answer: You must consult the judge, or the mufti of the country, with the presence of the wife and the presence of her wali (guardian), and the presence of your mother, so that he may look into your case and issue a ruling for you regarding what is obligatory; because this matter requires detail and care. So you must consult the judge, who is the shaykh who is the ruling authority in the Shari'ah, or the mufti in the country, in the presence of the wife, her wali, and your mother, so that he may look into the entire reality and issue a ruling for you regarding all of it, if Allah wills. Yes.
The presenter: May Allah reward you.
