He mentioned those who had only one hadith and those who did not

Translation

This book by Al-Hasan Al-Khallal is one of the hadith parts. It addresses those who only had one hadith and those who did not narrate from their sheikh except one hadith. In this work, Al-Khalal shows the hadiths of some narrators who only narrated one hadith, or only narrated one hadith on the authority of their sheikh, which indicates the importance of those hadiths in documenting the chain of transmission of the hadith and the authenticity of its transmission.
