What is the interpretation of finding Ayat al-Kursi in the questioner's trousers, and is this related to the problems that occurred between him and his fiancée, and what should he do?

The suitor is a stranger to his fiancée before the marriage contract. If a paper containing Ayat al-Kursi is found, it must be kept in a befitting place and not discarded, because it is Quran and holds its sanctity. One should not hasten to attribute problems to magic; rather, one should search for apparent causes and address them, avoiding doubts and delusions. When a person is afflicted with a tribulation, he should review himself and renew his repentance to Allah, for sins and disobedience are a cause of tribulation. As Ibn al-Qayyim mentioned, the punishments for sins remove blessings and bring about calamities.
