How can one get rid of the effects of old magic found 20 years ago that has caused recurring problems, such as delayed marriage and reluctance to propose?

Delayed marriage can be an affliction that raises one's ranks and expiates sins. It is advised to be patient and to turn to Allah through supplication. For treating magic, Surah Al-Baqarah should be recited, and one should seek help from righteous people for Ruqyah Shar'iyyah, while emphasizing the importance of continuously reciting the Quran for protection and reward. To get rid of written magic, refer to Fatwa no. 91693.
