What is the ruling on remaining with a husband who is negligent in spending, curses the religion, refuses to allow his sick daughter to be examined by a doctor, and mistreats his wife and her family?

The spouses erred in their choice. The wife should diligently search for a suitor whose religiosity and character are pleasing. Cursing religion is a grave matter and an act of disbelief. Thus, the wife is not permissible for her husband if he curses religion, until he repents. The husband must treat his wife kindly and spend on her and their child equitably. The spending is estimated to be sufficient for food, drink, and clothing. He is not obligated to give his wife an allowance unless he wishes to do so. If he falls short in providing maintenance, she is permitted to take what suffices her and her child from his money without his knowledge.
