I read a response from your eminence stating that it is permissible for a woman to stipulate to her husband that he not marry another woman!

Question:
He says: Honorable Shaykh, may Allah grant you success. I read a response from your eminence in one of his other answers that it is permissible for a woman to stipulate to her husband that he not marry another woman. Did I read it? As I read it.

Answer:
Yes, this is a valid stipulation. She has a valid purpose in this; she does not want a co-wife, and she has a valid purpose in this. If he violates it and marries another, he may do so; he is allowed to marry. However, she has the option: if she wishes, she may remain with him despite the presence of the co-wife, and if she wishes, she may request the annulment to remove the co-wife from her. Yes. The Prophet (peace and blessings be upon him) said: "Muslims are bound by their stipulations." Yes.
