Does an oath sworn on the Qur’an to abstain from sexual intercourse and travel together in Jordan become binding if the girl travels alone, then they meet later, travel, and engage in sexual intercourse in Jordan?

Immediate repentance from this sinful relationship is obligatory, for procrastination in repentance is not permissible, and it is another sin. Your knowledge of the prohibition of fornication coupled with your engaging in it is a serious matter. A woman traveling alone does not break an oath, but your traveling together obligates you to make expiation. You must hasten to repent and sever the relationship with this girl. You may marry her after repentance and ensuring she is not pregnant, if you both desire.
