Is it permissible to break off an engagement upon discovering repeated lying and deception on the part of the fiancée and her family, even if there is an attachment to her?

If a woman safeguards her prayers, performs her religious duties, and abstains from prohibitions, there is no impediment to marrying her, even if she is a liar. It is advisable to remind her of the seriousness of lying. However, if she is negligent in her duties and abandons her obligatory acts, then one should not marry her. It is permissible to annul an engagement with or without a reason, but annulment should not occur unless there is a strong justification.
