Ṣaḥīḥ al-Bukhārī is unsurprisingly the most widely recognized book among Muslims after the Qurʾān. Curious readers of Bukhārī's magnum opus are often left with burning questions that lie beyond its contents. Who was Imām Bukhārī? How and why did he write the Ṣaḥīḥ? How was it transmitted? Are there any reliable extant manuscripts of the work? In this introduction, Dr. Muṣṭafā al-Aʿẓamī answers these questions in a simple and accessible manner. This translation, alongside added annotations and appendices, presents and expands on al-Aʿẓamī's research for an English readership, for whom there is a dearth of resources on the subject.
