Does the guardian have the right to prevent a woman's marriage for a legitimate harm?

Question:
If the guardian sees that there is a legitimate harm in this marriage, does he have the right to prevent her from marrying this man?

Answer:
He must strive in this matter and not marry her off except in a way that brings her good and benefit. If they disagree, they should return to the court. However, it is incumbent upon him to strive; he must not marry her off except to a righteous man whom he considers suitable for her.
