Is it permissible for the fiancée to travel to her fiancé's family in another country (Egypt), while he is traveling to a third country (UAE), especially after they committed Zina and repented, and to prove her love for him?

Adultery is a grave indecency and a major sin. It has been coupled with polytheism and unlawful killing in the Quran. The woman who committed adultery must repent to Allah with sincere repentance. Allah accepts the repentance of those who repent, and He forgives all sins. It is forbidden for a woman to travel without a mahram. A fiancé is a stranger to his fiancée until the legal marriage contract is concluded. The adulteress's attachment to the man with whom she committed adultery and her desire to travel to him, under the pretext of proving love, are steps from Satan to lure her into disobedience. She must abstain from anything that leads to seclusion with this man or uncovering in front of him, as he is a stranger to her.
