Hadith studies

Hadith studies (Arabic: علم الحديث‎ ʻilm al-ḥadīth "knowledge of hadith" or science of hadith) are a number of religious disciplines used in the study and evaluation of the Islamic hadith (the collections of the reports of what the Islamic prophet Muhammad said verbatim on any matter) by Muslim scholars. It has been described by one hadith specialist, Jalal al-Din al-Suyuti, as the science of the principles by which the conditions of both the sanad, the chain of narration, and the matn, the text of the hadith, are known. This science is concerned with the sanad and the matn with its objective being distinguishing the sahih, authentic, from other than it. Ibn Hajar al-Asqalani said the preferred definition is: knowledge of the principles by which the condition of the narrator and the narrated are determined.

Importance

A common historical method in Islam, hadith studies consist of a careful examination of the isnad, or chain of transmission accompanying each hadith.The isnad is carefully scrutinized to see if the chain is possible (for example, making sure that all transmitters and transmittees were known to be alive and living in the same area at the time of transmission) and if the transmitters are reliable. The scholars reject as unreliable people reported to have lied (at any point), as well as people reputed to be heedless (and thus likely to misunderstand the saying).

MATN2

Matrilin-2 is a protein that in humans is encoded by the MATN2 gene.

This gene encodes a member of the von Willebrand factor A domain containing protein family. This family of proteins is thought to be involved in the formation of filamentous networks in the extracellular matrices of various tissues. This protein contains five von Willebrand factor A domains. The specific function of this gene has not yet been determined. Two transcript variants encoding different isoforms have been found for this gene.

Matrilin-3 is a protein that in humans is encoded by the MATN3 gene.

This gene encodes a member of von Willebrand factor A domain containing protein family. This family of proteins is thought to be involved in the formation of filamentous networks in the extracellular matrices of various tissues. This protein contains two von Willebrand factor A domains; it is present in the cartilage extracellular matrix and has a role in the development and homeostasis of cartilage and bone. Mutations in this gene result in multiple epiphyseal dysplasia.
