Is *mahr al-mithl* (dower equivalent to that of comparable women) obligatory if consummation occurred in a void marriage that is not recognized under Islamic law?

Primary text

If consummation has occurred in such a void marriage, the obligation for *mahr al-mithl* is determined by the two differing narrations (*riwayatayn*) concerning the ruling on a Muslim man who has sexual intercourse with one of his prohibited female relatives (*mahārim*) due to a legal ambiguity (*shubhah*).
