Is it permissible for the wife to buy land and travel without her husband's knowledge, to visit her family before her husband does, to hide her expenses, and to disobey his command in matters such as travel and certain types of clothing?

It is permissible for the wife to purchase a piece of land with her own money without her husband's knowledge. However, her traveling without his permission or consent is not permissible and is considered an act of disobedience and insubordination (nushooz). The wife must remain in her husband's home and not leave except with his permission, even to visit her parents. The wife is not obligated to inform her husband about her possessions or how she spends her money, but it is preferable to inform him. The wife must obey her husband in what is good, and contradicting him in matters such as travel and modest dress is forbidden. It is advised to treat the husband with kindness and to reside with him in his country, even if it requires leaving one's job.
