How does the matn of a hadith differ from its isnad?

In the study of Hadith, the isnad and the matn represent two distinct but complementary components of a report.

• Isnad: This is the chain of authorities or transmitters who relayed a specific statement, action, or approbation of the Prophet Muhammad, his Companions, or later authorities. It serves as the "support" for the report, and its reliability is the primary factor in determining the authenticity of a hadith.12
• Matn: This is the actual text or content of the report itself. It contains the substance of what was said or done.12

The isnad typically precedes the matn in a report, functioning as a verification mechanism. While scholars scrutinize the isnad to ensure the chain of transmission is continuous and composed of trustworthy individuals, they also evaluate the matn to ensure it does not contradict orthodox belief. A hadith is classified as sound (sahih), fair (hasan), or weak (da'if) based on the combined integrity of both its chain of transmitters and its textual content.123
