What is the ruling on the first wife refusing to share a single home with the second wife and her demanding a divorce if they are brought together in one home, and what is the ruling on the husband if he forces the first wife to do so?

A wife has the right to an independent dwelling, and she cannot be forced to live with a co-wife or the husband's relatives, due to the potential harm and distress this may cause. The jurists agreed that it is not permissible to house two wives in one dwelling unless they both consent. Some even went further, stating that this right does not cease even if the wife consents. An independent dwelling is achieved with a private room having its own door and lock, along with a private bathroom and kitchen, unless the husband is among the poor who accept sharing a kitchen and toilet. The first wife has the right to refuse to live with the second wife, and she may request a divorce if the husband insists on it. The husband commits a sin if he forces her to share a dwelling.
