What is the ruling of Islamic law concerning a husband who does not provide for his wife and children and mistreats his first wife after marrying another, and is he entitled to ask her for money, and is it permissible for the wife to refuse to obey him, and what is the Islamic legal guidance for the wife in this situation?

A wife's salary is her private property, and the husband has no right to it unless he stipulated this condition in exchange for allowing her to work. It is obligatory for the husband to provide for his wife and children and to be just among his wives, and his failure to do so is a sin. It is not permissible for the wife to refuse her husband's conjugal rights. She has the right to demand her rights and to take her case to court. The wife is advised to fear Allah and address the problem through lawful means, and the husband is advised to fear Allah, spend [on his family], and be just.
