because they have it on everything else. Adultery = Stoning to death
The Qur'an has a different punishment for witnessed and proven adultery. A set number of lashings and letting the adulterous couple live with one another in peace after their punishment.
The Hadiths try to imitate the laws in the Bible more maybe, which differ from the Qur'an.
Yet, none of that matters, so why not just come right out and say what has got your heart feeling bad, that Islam is rubbish, you hate Islam, you hate Muslims, you think they are corrupt and their religion is rotten. No need to be chicken about it (they eat chickens a lot), be a man.
You don't like Islam, you don't care about Islam, you just want Islam to go away. Unfortunately, there are only so many "Richerds" and billions of people identifying as Muslims. You're out numbered, by far, which might explain why you feel the need to slither around and pretend to be worried about Muslim women's broken arms.
I think "stoning to death" for adultery, is a very harsh punishment, one that was practiced by all the "Abrahamics" before Islam, are you on of the "Abrahamics"? If you are, you're likely a hypocrite, like most of them. See? I'm teaching you how to be a tough guy, and not crawl around like a rat or mouse, pooping here and there and everywhere.
Or are you a (militant) Atheist? Then Islam isn't your problem specifically, but all religions should be, or do you typically start with whatever seems "brown" and then move to "yellow" and finally on to "white"?
So, I don't know what "Islam" has to say about breaking arms, except that the Qur'an says not to even raise your hand in violence towards anyone, except in self defense. Most governments and countries these days have laws that are meant to protect and defend people who are the victims of violence and crime, but surely there are wife-beaters who associate with every religion.
Maybe, if some of the "other browns" are right, you'll reincarnate as a Muslim wife who gets her arm broken by her thug of a husband, and then you can come back onto this forum (haha, I'm pretty sure it won't exist and all my writing will be deleted yet again!) or whatever new one, as "Richeda" and tell us all about how Islam doesn't have specific laws that helped you and your arm.
In fact, I think that your punishment should be that your (surely well intended question, no?) be answered as thoroughly as possible by your reincarnation into a Muslim little baby girl who grows up into a Muslim wife who marries some hot shot bad boy who ends up being extremely abusive and breaks your arm on purpose, then you'll really have the answer you seek, no?
Then maybe that evil man, as abusers may tend towards, also finally ends your life (Does Islam have any law against a Husband murdering his wife? No, nowhere in the Qur'an does it specifically mention a Husband murdering his Wife, must not mean anything to people durrrrr DURRRRR DURRUDU DDURRRRRR I AM FUL OF HATE DURRRR IM SO FULL OF HATE DURRRR (an impression of me, not you)), and then you reincarnate as a man who is abusive (or are you that already "Richerd"? Naughty boy, you like violence don't you? You like agitating people and getting violence to occur don't you? Huh, tough guy? You came itching for a fight, didn't you big boy?), and you break your wife's arm.
Oh wait, you're also a Muslim in that scenario. Then you think to yourself "hmm, this isn't so bad, afterall, as a violent and abusive man, I can snap my wife's little crab-leg arm and get away with it, because Islam lacks any particular law regarding snapping a wife's arm, bwuahaha, and I even found this stupid irrelevant seeming Hadith to back me up bwuahahah! Who do I have to fear and what recourse do they have against me! Evil Muslim Richerd! I am Immune to Punishment, and there is in fact no God who minds my snapping the arm of my wife! How good it felt to snap it! I should snap the other, and her legs too! Bwuahaha! I know so much about Islam! It saves me from morality entirely! I love being an Evil Muslim!
So, now you have it all, you understand why people are Muslims, it is so that they can snap their wives arms and get away with it, and many other evil deeds, which their God rewards them for most likely.
Are you satisfied Richerd? You've now lived as a Muslim Woman (how was the sex?) married to a violent and abusive man (in bed too?) and you've lived as an Evil Muslim Man who snaps his wife's arm (felt good didn't it?), and finally understand everything about everything you really wanted to know. Allah hu Ackbar!
The Qur'an is a scripture, a religious book, not a complete legal system for every nuance of criminal act, which has to be decided by the people, by the families, by the individuals, by the governments, etc, and these governments and peoples may all differ among themselves and have varying laws and requirements. Nowhere in history as far as I'm aware was it considered just hunky dory to purposefully break your own wife's arm as any sort of punishment or anything. The family of the wife was often still around, and might take vengeance upon you if they found you hurt their daughter or sister or whatever, you nasty man (I'm talking to Evil Muslim Arm Breaker Richerd, not curious snake innocent rat Richerd, or even you, I like you and I like the coward as well, more than Evil Muslim Arm Breaker Richerd, he is scary and mean, and so brown that I can barely see him when he stands in front of a UPS truck).
