Hadith speech of a person. In Islamic terminology, according to Juan Campo, the term "hadith" refers to reports of statements or actions of Muhammad, or of his tacit approval or criticism of something said or done in his presence. Classical hadith specialist Ibn Hajar al-Asqalani says that the intended meaning of "hadith" in religious tradition is something attributed to Muhammad but that is not found in the Quran. Scholar Patricia Crone includes reports by others than Muhammad in her definition of hadith — "short reports (sometimes just a line or two) recording what an early figure, such as a companion of
Hadith terminology in and of itself"with the same definition a "ṣaḥīḥ hadith" except that the competence of one of its narrators is less than complete; while a "hadith" that is "ḥasan ligharihi" ("ḥasan due to external factors") is determined to be "ḥasan" due to corroborating factors such as numerous chains of narration. He states that it is then comparable to a "ṣaḥīḥ hadith" in its religious authority. A "ḥasan hadith" may rise to the level of being "ṣaḥīḥ" if it is supported by numerous "isnād" (chains of narration); in this case that "hadith" would be "ḥasan lithatihi" (""ḥasan" in and of itself")
