Proposing to an engaged woman

Q: A man proposed to the parents of a girl to marry their daughter, and they agreed. Three years later, the concerned man and his fiancée agreed to conclude the contract of their marriage. However, one week later another man appeared and proposed secretly to the parents of the same girl to give the latter to him in marriage. The parents agreed to the marriage proposal of the second man and married their daughter to him. Please tell us whether this is permissible or not?

A: If the reality is exactly as you have mentioned, the marriage contract that was concluded by the girl's father for the second fiancé of his daughter is valid. However, the marriage proposal of the second man is impermissible if he knew about the first fiancé and the family's approval of him. Otherwise, the marriage proposal of the second man is permissible. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
