What is the ruling of Islamic law regarding a wife remaining with her husband who does not work, borrows money from her family without repaying it, disbelieves in Allah, curses the religion, does not pray, and is ill-tempered? And should she be patient with him for the sake of her children?

Cursing the religion or cursing Allah is an act of disbelief that expels one from the fold of Islam. It is not permissible for a woman to remain with a man who disbelieves in Allah and curses the religion; rather, she must separate from him immediately. His case must be brought before a judge. The wife's money is her property, and the maintenance of the wife and children is obligatory upon the husband.
