I agree with her keeping it 100%. I am Muslim. In Islam, a woman gets half the inheritance of her brothers. But that is because she is entitled to keep it entirely for herself. A man is obligated to provide for his wife and children. I understand not everyone would agree with our religious ruling, but this is also a case of how he made the rules first. Now he has to live by them. Honestly, I could not be married to a man who was so greedy and kept his inheritance from helping his children. But no matter what, she shouldn't give him a cent!
