What is the religiously mandated frequency for a wife to visit her brother weekly, and what is the religiously mandated frequency for a wife to visit her mother during the annual holiday?

Religion encourages maintaining kinship ties and warns against severing them. Islamic law has not specified the exact extent or nature of maintaining kinship ties; rather, it refers to common practice in this regard. If the custom in a country dictates visiting a brother every week and staying with one's mother for a week each year, then this custom should be followed. It is generally sufficient for a woman to stay with her mother for seven days to fulfill the obligation of maintaining kinship ties, unless her mother is ill, and the husband is not obligated to permit more than that. It is advisable for both spouses to exercise wisdom, gentleness, and overlook causes of disagreement, for Allah has commanded kind treatment. A woman should maintain ties with her kin and be eager to visit them, but not at the expense of her responsibilities in her husband's home, and the default is that her decision-making authority lies within her own home.
