Sunan at-Tirmidhī

About this collection

A student of al-Bukhārī, at-Tirmidhī created the vocabulary the hadith sciences still use today. His Sunan is uniquely valuable because each hadith is accompanied by a discussion of its chain, its meaning, and how the different legal schools handled it — a textbook within a collection.

Methodology

at-Tirmidhī innovated a grading terminology — ṣaḥīḥ, ḥasan, ḍaʿīf — that became the standard of the entire hadith tradition.
