Hadith terminology (muṣṭalaḥ al-ḥadīth) is the body of terminology in Islam which specifies the acceptability
of the sayings (hadith) attributed to the prophet Muhammad and other early Islamic figures of significance,
such as Muhammad's family and/or successors. Individual terms distinguish between those hadith
considered rightfully attributed to their source or detail the faults of those of dubious provenance. Formally,
it has been defined by Ibn Hajar al-Asqalani as: "knowledge of the principles by which the condition of the
narrator and the narrated are determined." (Muhammad, 2008)
