Is it permissible for a repentant Muslim man to marry a repentant Christian woman who wishes to embrace Islam, knowing that both of them committed adultery and she desires to live in a Muslim country?

If the girl embraces Islam and repents with sincere repentance, there is no objection to your marriage, for her conversion to Islam expiates what preceded, as Allah Almighty says: "Say to those who disbelieve, if they cease, what has passed will be forgiven for them," and as the Prophet, peace and blessings be upon him, said: "Do you not know that Islam demolishes what came before it?" We hope that your sin will be forgiven through sincere repentance, as Allah Almighty says: "Except for those who repent, believe and do righteous deeds, for those Allah will change their evil deeds into good ones." Therefore, cut off contact with her, strive to guide her to Islam, and then marry her.
