[Abū Īsã Maḥommed ibn Īsã ut-Tirmidhī]. Arabian traditionalist, born at Tirmidh on the Jiḥūn. He was a scholar of the traditionalist Bukhãrī, and in his search for traditions travelled through Khorasan, Irak and Hejaz. His al-Jãmi us-Ṣaḥiḥ is one of the six canonical collections of traditions. In it he admitted every tradition that had ever been used to support a legal decision, indicating the doctrine it supported and mentioning the doctrines opposed to it. It was published at Bulaq in 1875. He also wrote the Kitāb ush-Shamail on the character and life of Mahomet (printed at Calcutta, 1846).
