Marrying A Woman Who Doesn't Offer Salah
I am not aware of any such reported incidents relating to Salah, had such a situation occurred at that time, then the ruler of that time had authority to decide for each such individual after taking into account all the circumstances of the case, since Salah and Zakat were made a mandatory expression of their faith at that time to prevent them from death. Abu Bakr (rta) took action against Zakat rejectors on the same basis.
