Al-Tirmidhi, Persian scholar and hadith compiler (born 824)

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.

In Islam, the ulama are scholars of Islamic doctrine and law. They are considered the guardians, transmitters, and interpreters of religious knowledge in Islam.

Hadith is the Arabic word for a 'report' or an 'account [of an event]' and refers to the Islamic oral tradition of anecdotes containing the purported words, actions, and the silent approvals of the Islamic prophet Muhammad or his immediate circle.
