Does the wife rightfully deserve full financial support if her husband divorces her due to her dishonesty, repeated lying, and continuous negligence, despite his advice to her?

The traits mentioned in the woman are blameworthy and forbidden by Islamic law. She must repent from them by restoring rights. As for her maintenance after an irrevocable divorce, she is entitled to neither maintenance nor housing. As for her maintenance before the divorce, her lying, stealing, and lack of self-care do not preclude the obligation of providing her with maintenance, unless she is disobedient (nashiz).
