The oath not to reconcile with the husband and the expiation for the oath

Question:
This is a letter from one of the sisters. She says: Shaykh, there is a man married to two women, and he is inclined toward one of them. He has boycotted the bed of the first wife for many years. When he returned to her, she swore an oath that if he did that again—even if he were to visit his second wife for the least amount of time—and if he did not visit her, she would not forgive him. So the man returned and boycotted the first wife again. Now he is asking for forgiveness and wants to return to her, but she is hesitant. Should she return to him or not? Because she swore an oath, should she forgive him?

Answer:
This is a private matter that they settle between themselves. If she swore that she would not reconcile with him, she must expiate her oath by feeding ten poor people, or clothing them, or freeing a slave. If she cannot find the means to do so, she must fast for three days and reconcile with her husband. Yes.

May Allah reward you.
