What should a husband do whose wife suffers from extreme jealousy towards his brothers' wives, to the point that she refuses to visit his mother when they are present, which has affected his relationship with his mother, and should he divorce her or preserve his marriage for the sake of their daughter?

Firstly: The wife has the right to a private dwelling, and you did well by refraining from joking with your brothers’ wives.

Secondly: Honoring one’s parents takes precedence over all else. Disobeying your mother is not permissible in any way; rather, you must honor her and prioritize loving her.

Thirdly: Since your wife is a woman of good character and religious devotion, preserve your relationship with her and address the issue with wisdom and patience. Explain to her the rights of a mother and her great status, and that her رضا (pleasure/satisfaction) is from the رضا (pleasure/satisfaction) of Allah.

Fourthly: It is not permissible to abandon your mother or reduce your visits to her. You can visit her alone and bring her gifts secretly from your wife, or occasionally bring her to your home.

Fifthly: The solution lies in wisdom and good management. Honor your mother and do not contemplate divorcing your wife.

Sixthly: The wife must alleviate excessive jealousy, and the husband must appreciate his wife's love for him and avoid mentioning divorce.
