Return 404 when Hadith data is empty or missing (#3201)

* fix: handle empty hadiths data in getStaticProps

Added a check in getStaticProps to return a notFound response if the hadiths data is empty, ensuring proper handling of cases where no hadiths are available for the requested chapter.

* refactor: simplify empty hadiths check in getStaticProps
