About Muhammad ibn Isa at-Tirmidhi
Muhammad ibn Isa al-Tirmidhi, often referred to as Imām at-Termezī/Tirmidhī, was an Islamic scholar, and collector of hadith from Termez. He wrote al-Jami` as-Sahih, one of the six canonical hadith compilations in Sunni Islam. He also wrote Shama'il Muhammadiyah, 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.
