Among the sciences of Hadith is the study of the Chain of Reporters (the Isnaad). Many Muslim scholars have specialized in this field. It includes identifying the name of each and every narrator (reporter), his character (his truthfulness, piety, public behavior), his ability and reputation as a memorizer and the types of narrations he is known to report, whether authentic, weak, fabricated, etc. This article titled, Significance of Knowing the Narrators of Prophetic Hadith, shows the importance of realizing and considering the significance of this field of knowledge.
