Is it permissible for a wife who is suffering in her home due to lack of privacy and safety, and her husband’s neglect, to go and live with her family against her husband’s will, as he does not give her permission, until suitable housing is provided or separation occurs, especially given that her current situation is affecting her health and forcing her to disregard the doctor’s instructions?

It is the wife's right to have an independent and suitable dwelling, meaning a separate part of the house with its own facilities. The husband is not obligated to equalize between his wives in maintenance and gifts; rather, he is required to fulfill each wife's right and spend on her in a reasonable manner. If a woman has an independent dwelling with its own facilities, she does not have the right to request another, unless it is unsuitable and causes her harm. In that case, she has the right to request a suitable dwelling. Otherwise, she remains in her family's home until a suitable dwelling is provided for her.
