Faskh of nikaah
Q: In shariah law there is a system called Faskh e Nikah which allows a woman who is abused in a marital relationship and has legitimate reasons to end the marriage can do so through a judicial decree without consent of her husband.
I would like to know is this system proven from Quran, Sunnah and Hadith?
Secondly, what are the legitimate reasons that will allow a Muslim woman to exercise her right to annul the marriage through this system ?
