Sahih Bukhari or Sahih al-Bukhari (Arabic صحيح البخاري) is one of the six canonical hadith collections considered to authentic by the Sunnis. These hadith were collected by a Persian Muslim scholar named Muhammad ibn Ismail and called Bukhari after his birthplace Bukhara. The hadiths of the Prophet Muhammad were previously transmitted orally. Sunnis consider it one of the two most trusted Hadith collections, the other being Sahih Muslim, and the most authentic book after the Quran.
