Is the marriage of a Muslim woman to a non-Muslim considered apostasy, and does it disqualify her from inheriting from her father?

The marriage of a Muslim woman to a disbeliever is invalid and is considered illicit sexual intercourse, not a marriage. The woman does not become a disbeliever merely by committing fornication with him, and she inherits from her father unless she considers this forbidden act permissible; in that case, she becomes a disbeliever, unless she is a recent convert to Islam or grew up in an environment where ignorance prevails. If she apostatizes and then repents and returns to Islam, and her father dies while she is a Muslim, she inherits from him.
