How can a young man who is engaged definitively rid himself of the torment of doubt and anxiety resulting from an anonymous message accusing his fiancée, knowing that he has asked her close acquaintances and confirmed the falsity of the claims, and has consulted the imam of his mosque?

No attention should be given to a message intended to create discord between you, as it could be from a woman who desires the suitor for herself or envies them, or a man who desires her for himself or envies them, or one of those who cause mischief. The important thing is to consider the girl's current good character, uprightness, and chastity, not her past. Continue with your engagement if she is of good character and religious commitment.
