The ruling on a wife visiting her parents on a day that is not her turn?

Question:
He says: Honorable Shaykh, may Allah grant you success. The author of the book *Kashf al-Mukhaddirat* says in his commentary on the issue of dividing time between wives: “It is forbidden to enter upon a wife on a day that is not her turn, or during her day, except out of dire necessity or pressing need, such as visiting a sick person or the like.” What is forbidden? It is forbidden to enter upon a wife on a day that is not her turn, or during her day, except out of dire necessity or pressing need. The question is: Does this apply if the husband’s father is with his first wife? Is he allowed to come to them daily and sit with them, or is he not allowed to do so?

Answer:
He is allowed to do so, because coming to his parents is not the same as coming to her. Yes, he may come to his parents.
