Is the chaste Nazarene meant to be the virgin Nazarene? And is it permissible to marry a Nazarene woman who has previously committed adultery, and if her repentance is obligatory, how should it be?

It is permissible to marry a chaste Christian woman who has not committed fornication. The loss of virginity is not considered proof of fornication, as it can be lost due to other reasons, and a woman may commit fornication without losing her virginity. It is better for a Muslim man to marry a righteous Muslim woman who will assist him in his religious life and in raising his children.
