Deceit and lying are not a justification for anything, single or multiple marriages. The judge can annul the marriage if such things are done to trick the person into marriage. If a woman stipulates that she be informed before he takes any wives then it's not that he should respect that, but he HAS to inform her. That was one of the conditions for the marriage he agreed to before marrying so he has to fulfill that unless she states otherwise. Same way with caring for her.
Nikah is the marriage contact just you have business contracts and every contract has conditions that can be put in before it is signed. The Prophet (sallallahu alayhi wassalam) said that these nikah contract conditions are more deserving to be fulfilled since they make man/woman permissible for each other. He cannot "return" her to her ex-husband. She is not a property. He can only divorce her and then it is her decision alone to marry whom so ever she chooses. If this man is doing such things then doesn't the community of such a man? sisters should be informing other sisters so they are protected from such a person. It seems like this person just wants to derive pleasure from as many women as he can without giving them their rights. It seems even more a true argument if he's involved in zinah with non-muslim women also. A person cannot make marriage such play thing. Like I mentioned before, the woman need to do their research properly since they are the ones who will be affected more with what happens in the marriage. They need to make sure the person is a good person and not pretending to be one. Especially when it involves polygyny. Interview the man's current and ex wives. If he is good then he has nothing to worry about if he has something to hide then he will dislike the idea. Re: Proper ruling on multiple marriages Posted by: "J M" J M jmugh786 Fri Sep 19, 2008 6:19 pm (PDT) Waalaikum'Salaam, No one is questioning what is Sunnah in terms of the limits on wives (for the man), but deceit and lies are not a part of justifying multiple marriages. If the woman stipulates that she has a right to be informed before and not after the marriage, then this should be respected. This brother promised to care for his wife before marriage then refused to care for her after the marriage was completed. But, a few of the others (who he still calls his wives) benefit fully from their marriages with him. It is haraam to show favor of one wife over another! When he is tired of that wife (as he did to one sister), he simply got permission to return her to her ex-husband and left to marry another one. Just for your information, the "7th" is just a number and does not include the non-Muslim women he associates along with his wives. Haraam! j786SURAH22
