Why were the visions not fulfilled, which were seen by both the questioner and her fiancé, and which were interpreted to them as abundant good, after the engagement was annulled?

The hadith was authenticated by Al-Hakim, Al-Dhahabi, and Al-Albani, and its application is when the dream is truthful and its interpretation is correct. We advise you to repent to Allah and turn your heart away from attachment to this man.
