What is the ruling on the marriage contract of a Muslim man to an apostate woman who did not inform him of her apostasy and did not repent until after the marriage?

It is not permissible for a Muslim to marry an apostate woman. If such a marriage occurs, it is invalid, and the marriage contract must be renewed after her repentance and return to Islam. Children born from this invalid marriage are attributed to their father if he believed the marriage to be valid, because "the child belongs to the bed."
