What is "al-tirmidhi"

Abū ‘Īsá Muḥammad ibn ‛Īsá as-Sulamī aḍ-Ḍarīr al-Būghī at-Tirmidhī (; , Termezī; 824 – 9 October 892), often referred to as Imām at-Termezī/Tirmidhī, was a Persian

Islamic scholar and collector of hadith who wrote al-Jami` as-Sahih (known as Jami` at-Tirmidhi), one of the six canonical hadith compilations in Sunni Islam. He also wrote Shama'il Muhammadiyah (popularly known as Shama'il at-Tirmidhi), a compilation of hadiths concerning the person and character of the Islamic prophet, Muhammad. At-Tirmidhi was also well versed in Arabic grammar, favoring the school of Kufa over Basra due to the former's preservation of Arabic poetry as a primary source.
