Muhammad ibn Isma'il al-Bukhari, commonly referred to as Imām al-Bukhāri or Imām Bukhāri, was a 9th-century Muslim muhaddith who is widely regarded as the most important hadith scholar in the history of Sunni Islam. Al-Bukhari's extant works include the hadith collection Sahih al-Bukhari, Al-Tarikh al-Kabir, and Al-Adab al-Mufrad.

Born in Bukhara in present-day Uzbekistan, Al-Bukhari began learning hadith at a young age. He traveled across the Abbasid Caliphate and learned under several influential contemporary scholars. Bukhari memorized thousands of hadith narrations, compiling the Sahih al-Bukhari in 846. He spent the rest of his life teaching the hadith he had collected.
