Husband becoming a Sikh

Q: I am thinking about marrying a woman who has a son already from a different person who is a sikh. I know its not allowed to marry someone out of religion. But the person who was married to her converted to Islam and did nikah but after couple of years he turned back to sikhism. Now the problem is where she stands at the moment. And she is also not divorced by him too. So can I still do nikah with her because its also not allowed to do nikah on top of the nikah as I know according to Islamic point of view. Moreover she is older than me almost 17 years but my intention is only to ease her problems and give her a happy life. Your advise will also help me a lot in this matter.

Wife taking her share from the husbands money

Q: My friend and her husband are in their 60s. Children all married. They had a big house both of them owned because both worked hard to buy that house and they lived in this house for a long time Alhamdulillah. Now her husband retired and he sold the house and they now travel or live with their children one by one. He kept all that money in a secret account. She did not get anything. She wants to know can she take little by little from him without telling him? If she ask he won't allow her. But if she takes it without telling him he will never find out. Is this ok to take her share little by little without telling him. Please respond.
