A Muhaddith (Arabic: محدث) is a scholar specialized in the study, collection, and interpretation of hadiths, which are the recorded sayings, actions, and approvals of the Prophet Muhammad. The role of a muhaddith is central to the science of hadith (ʻilm al-ḥadīth), a key field for understanding and preserving Islamic teachings and laws. Muhaddith can either disseminate the hadiths or compile them into an ahadith. Source: Wikipedia (en)
