Can a wife prevent her husband from taking more wives?
This is a much needed admonition to the muslimaat upon the sunnah, and may Allaah grant both men and women the akhlaaq (manners) to deal with such situations. shaykh al-albaani (rahimahullaah) says:
“Of course, I believe that that is not allowed for (the woman) (to come between her husband and polygyny) because of two reasons:
The first (reason) is that she is hindering (her husband) from the path of Allaah, and other (reason) is that she is opposing the command of her husband. Because you know…that the obedience of a woman to her husband is obligatory the way the matter is with regard to the obedience of an individual from the individual members of a nation toward the Muslim ruler, with an obedience which I don’t say is blind but rather a complete obedience, except what is made an exception in the islamic legislation, which is (obeying someone) in disobedience to Allaah. And from this results islamically legislated rulings which (state) that if the Muslim ruler commands that which is fundamentally allowed, this command becomes obligatory for the one who is commanded with it to carry it out, because it is the command of the ruler. Exactly likewise is the command with respect to the husband with his wife.
So if the husband commands his wife with some command while that command is allowed in the foundation of the islamic legislation and while the woman is able to carry it out, then it is obligatory upon her to obey him. And if she does not obey him, then she has disobeyed Allaah and His Messenger [sallAllaahu 'alayhi wa sallam].
So, concerning that which the woman undertakes of using hindrances that come between her husband and that which he wants to attain from what Allaah, the Mighty and Majestic, has allowed, let alone if the allowed (matter) is that which is desirable (and) permissible, then no doubt she will be disobedient twice over.
The first time is that which preceded when I mentioned that indeed she is cutting off the path (of Allaah); and the other matter is that she is opposing her husband in a command that she has no right to oppose while she is able (to obey his command) and while he is not commanding or not wanting to do (an act of) disobedience to Allaah.”

“PS : Webster’s New World Dictionary defines Polygamy as “the practice of having two or more wives or husbands at the same time.” Since Muslim women are not allowed to have two or more husbands at the same time, let’s find a better word: Polygyny. The same dictionary defines polygyny as “a practice of having two or more wives at the same time.” Polyandry (Greek: poly- many, andros- man) refers to a form of marriage in which a woman has two or more husbands at the same time.”
