Imam al-Bukhari

Muhammad ibn Ismail ibn Ibrahim al-Bukhari (194-256 AH / 810-870 CE) was the compiler of Sahih al-Bukhari, universally regarded as the most authentic book after the Quran. Born in Bukhara (in present-day Uzbekistan), he lost his father at a young age and showed prodigious talent for hadith memorization from childhood. By the age of ten, he had memorized the hadith of his local scholars, and by sixteen he had committed to memory the works of Ibn al-Mubarak and Waki ibn al-Jarrah.

Al-Bukhari traveled for sixteen years across the Muslim world, visiting Mecca, Medina, Baghdad, Basra, Kufa, Egypt, and the Levant to collect hadith from over a thousand scholars, including Ali ibn al-Madini, Ahmad ibn Hanbal, and Yahya ibn Main. From a pool of approximately 600,000 narrations he had memorized, he selected 7,275 hadith (including repetitions; about 2,602 without repetitions) that met his extraordinarily rigorous criteria for authenticity. His methodology required an unbroken chain of trustworthy narrators who demonstrably met each other, a stricter standard than any of his contemporaries.

Sahih al-Bukhari is organized by legal and theological topics, with al-Bukhari's chapter headings (tarajim) themselves regarded as a work of juristic genius. He also authored al-Adab al-Mufrad on prophetic manners, at-Tarikh al-Kabir on narrator biographies, and other works. Despite his fame, al-Bukhari faced political difficulties in his later years and was expelled from Nishapur. He died in the village of Khartank near Samarkand in 256 AH (870 CE). His Sahih remains the gold standard in hadith scholarship and the most studied hadith text in the world.
