What is the ruling on a woman who fasts, prays, and performs night vigil, but harms people with her tongue and ruins her children's homes?

If a person performs acts of worship with sincerity, especially prayer, Allah places a light of faith in their heart that shields them from indecency and evil, for indeed, prayer restrains from indecency and evil. The woman should review herself, as excellence (ihsan) is required in her relationship with Allah and His servants. Correct worship must have an effect on a Muslim's conduct. Oppressing and harming people are acts of indecency and evil, and whoever does so has borne a calumny and a clear sin, exposing themselves to Allah's wrath. Her children should advise her, pray for her, and gently forbid her from evil, as this is a form of showing righteousness to her.
