Is it obligatory to pay the mahr to a woman with whom a man committed zina and deflowered her, then repented of his deed?

If fornication occurs with the woman's consent, then, according to the majority of scholars, nothing should be paid to her. However, if it was by coercion (rape), then he is liable for that, and he must pay the compensation for her virginity, which is the difference between her dowry as a non-virgin and her dowry as a virgin.
