Is a wife's desire for khula so that she can be free and travel considered a sin upon her, and what advice is directed to her?

The fundamental principle is that a khul' (divorce initiated by the wife in return for compensation) is not valid without the husband's consent. However, if the wife is harmed and the husband refuses to grant the khul', the judge may rule in its favor. If the wife requests khul' due to harm or dislike of her husband, there is no sin upon her, and it is recommended for the husband to accede to her request. However, if the request for khul' is without a valid reason, it is not permissible for her. Preventing the wife from going out and traveling without a valid need is not among the reasons that permit khul'. The default is that a woman remains in her home, and it is disliked for her to go out without need. Spouses should strive for reconciliation and avoid separation as much as possible, especially when there are children.
