Topic: Reasons due to which Nikah breaks   (No-706)

I want to know the reasons due to which Nikah of Muslim breaks and what should be done once the Nikah is broken. Please let me know the reasons as well as the way to revert

It should be notes that Apostasy, Khula, Talaq-e-Bain causes nikah to break. To reestablish marital relationship, the Nikah should be renewed
