married to a man who beat and raped her for weeks after the wedding ceremony.
That’s just an Islamic Honeymoon.
This comes from the Islamic practice called mahr (bride price, usually mis-translated as "dowry").
The husband pays a price for the right to marry the girl and have sex with her. Officially, the amount is the girl's property, which she would keep in the event of divorce. In practice, I'm guessing all too often the girl's father holds onto the money "for safekeeping".
When a man has paid a respectable amount of money to acquire a sex slave, it's not surprising that he wants his money's worth.
This practice also produces a pathological Islamic society, with wealthy men buying multiple wives, and poor men being wife-less and sexually frustrated and cranky all the time.
