What is the ruling on marrying a girl who has aborted her fetus twice, and are her repentance and remorse sufficient?

Adultery and abortion are two grave crimes forbidden by Allah. This woman committed indecency and aborted two fetuses, which indicates her disregard for Allah's boundaries. As for you, you wronged yourself by committing indecency with her. Both of you must repent to Allah and sever your relationship with this girl. It is not permissible for you to marry her until she has sincerely repented, because marrying an adulteress is forbidden.
