Hi Gang
You lot haven't got the hang of a Muslim marriage yet have you? I know, it takes a lot of mental adjustment.
Firstly, no-one, husband or wife, is allowed to be violent through anger. You are not allowed to even kill in war due to anger. Anger is pride and we will answer for this to Allah. Please try to understand our level of faith, it is not like being scared of being arrested and going to prison IF we are caught. There is no escape from the knowledge of G-d, so there is no 'if'. G-d knows everything we do and why, we WILL answer for all of our deeds, every tiny one of them.
Does this mean it will never happen, of course not but if we are angry or violent then we must repent and make every effort not to do it again in the future. Does this mean my husband can beat me then go buy his friend something nice and all is forgiven - of course not. However, if my husband ever hit me through anger (that will be the day

) he can repent, ask for my forgiveness and resolve never to do it again. However he would have to treat me 'real nice' after that. Will Allah forgive him hitting me? Only Allah knows but my guess is that if he repents and never repeats this then it will show his humility and if I forgive him this will show my humility.
Does this mean Muslim women should forgive time and again, NO way. We are not expected to stay in a violent marriage.
Sorry it is a long post but I really would like you to understand. If I am in a violent marriage I can ask for a divorce, if my husband refuses I can go to my Imam for help. What will happen first is the Imam will establish if this is the first time my husband beat me, why he hit me and how severly. He will then speak to my husband to get the other side of the story. Now there are a few possibilities:
1. The Imam discovers that this is the first fight where my husband hit me but that he did this through anger because we had a fight about money or I burnt his favourite shirt ironing it ... whatever but it was a normal marital argument. The Imam will then speak to my husband and I, both seperately then together. He will explain to my husband that hitting me is not allowed and that if he is afraid of Allah and the Day of Judgement he must truely repent and refrain from this behaviour in future. I can hear you say Big Deal but for someone that knows the Day of Judgement will come and he must answer for his treatment of his wife this is a big deal. I would then be asked if I can forgive my husband and encouraged to do so, with lots of assurance from the Imam that my husband understands the errors of his ways.
Result - a marriage is saved and my husband understands his obligations in the future.
2. The Imam discovers that I am a good wife but my husband is regularly violent about petty things, he simply has a temper problem.
If I was agreeable the Imam would work regularly with my husband to try to refocus his faith, understanding and anger. This does not mean 'let's forget about the past and try not to do it again - oops you did it again you are very naughty but lets try again'. It would be about focussing his mind on the many teachings of our faith about caring for your wife and on the punishments of hell. Basically about re-educating my husband.
If I was not agreeable a 'council' of Muslims would consider my case, if they came to the same conclusion as my Imam they would dissolve my marriage even though my husband refused the divorce. This would be legally binding (in reality this takes a looooong time but I would go to stay with my family while this process takes its course). My husband would be punished for his beatings and the chances of him finding a new wife would be slim to zero (as we are instructed not to marry a wife beater).
3. The Imam establishes that every time my husband goes to work I run off to see the local butcher (please be aware that I always use the example of the butcher because I never, ever go there, I do not want anyone to think this is some kind of confession). My husband at first tried to explain my actions were against our marriage, against our faith and tried to behave in a caring way that stopped me from wanting to go to see the butcher again. After that failed he refused to sleep with me for a month but I still kept going to see the butcher. Eventually my husband had enough and slapped my bum, shouting at me that I am a hussy and my behaviour will not be tolerated. That is when I went to see the Imam - guess who is in trouble now
Not only have I damaged my own marriage but I have also caused trouble in our community. My husband has shown restraint, patience and care for our marriage bonds. I on the other hand have shown no respect for my marriage, my husband, our children if we have them or my community. The Imam would then establish why my husband does not divorce me, if it is for the right reasons and not just to punish me and keep me in an unhappy marriage then I will be the one to be re-educated and punished for my wicked behaviour. Of course the butcher would also be punished (even if he was not party to my flirting he had not taken action to stop it as is his duty).
Under these circumstances if my husband had hit my face and split my lip he would get a good telling off and must honestly repent but in reality I doubt he would be punished as his actions would be deemed understandable under the circumstances. There is only so far you can push someone before people see it as 'asking for it'. Strictly speaking though under Islamic law my husband should be punished for this level of violence under any circumstances, as it is not allowed to leave a mark on my body or hit me on the face, no matter what I do.
So I hope you can see the fairness in the system. It is not about giving permission to beat your wife up but about protecting people from sin, protecting the community from trouble. What if the butcher was married, how many people have been hurt by our behaviour?
I agree with Saltmeister, refusing sexual relations sometimes is part of a normal marriage but for a prolonged period it puts a strain on a marriage. This can lead to a frustrated spouce and the possibility/probability of adultery.
This brings us to polygamy. Much is said about the topic and many Muslims use it for the wrong reason but may I give you an example of where it can work for a marriage and society as a whole. As you know I am much older than my husband, so what if I just go off sex altogether? It does happen with some women of a certain age. What if I love my husband dearly but just can't be bothered with sex anymore. In the UK either my husband, who we are assuming loves me, has to accept a life without sex, have an affair or get a divorce and remarry.
In Islamic society this problem can easily be solved if my husband has the financial resources, as he can take a second wife. He MUST divide his time equally between us and treat us equally, so if he buys me a new carpet he must buy one for his other wife. Now, I still have the husband I love and enjoy spending time with but I am not obliged to have sex with him if he accepts that within our marriage. He can get his satisfaction with his other wife but still have his first wife that he dearly loves. His second wife would accept this because there is nothing to be jealous of and chances are we would be friends and visit each other because we are not in competition with each other.
The same does not work for women. If my husband has a problem in that department and cannot satisfy me I cannot take a second husband because of the question of parentage of any children that come from the second marriage. I can however divorce my husband if he is unable to satisfy me and remarry. Of course in this situation it would be better for me to stay in my loving marriage and my husband can learn other methods of providing my satisfaction, this would be better for everyone. It would also be a blessing for my husband as he would be unlikely to ever find a new wife, so would show love, patience and humility on my part.
Where I do not agree with polygamy is if you get everything you need from one marriage, then to have a second is just greed and pride. Most of the men I have heard of that have polygamous marriages do it for the simple reason of showing off to the community that they are a 'big man' and can have two wives, also for purely sexual reasons. How they will treat them fairly and avoid the punishment of Allah I have no idea.
This is what Islam teaches, that does not mean it is how all Muslims behave but I really hope you can see how it gives a fair solution to all problems and everyone involved.
