Sahih al-Bukhari is the widely accepted cornerstone of Sunni Hadith literature, compiled by Imam Muhammad al-Bukhari (d. 870 CE). This monumental collection is universally regarded by Muslims as the most authentic book after the Holy Qur’an, rigorously documenting the sayings, actions, and approvals (Sunnah) of the Prophet Muhammad ($PBUH$). Imam al-Bukhari famously employed stringent criteria for the acceptance of narrations, focusing on the impeccable character of the narrators and the confirmed chain of transmission (Isnad), thereby making it the primary source for deriving Islamic jurisprudence (Fiqh) and understanding Prophetic methodology. It remains an indispensable text for Islamic studies, Sharia law, and Hadith scholarship worldwide.
