Sahih al-Muslim صحیح المسلم

Sahih Muslim, compiled by Imam Muslim ibn al-Hajjaj (d. 875 CE), stands as the second most authentic collection of Hadith following Sahih al-Bukhari. This critically important work meticulously gathers the Sunnah (sayings, actions, and tacit approvals) of the Prophet Muhammad ($PBUH$). Imam Muslim is renowned for his systematic approach, particularly his emphasis on arranging the Hadith by subject matter and preserving the integrity of the chain of narrators (Isnad) by grouping different routes of transmission together. Sahih Muslim is a fundamental and indispensable source for Islamic jurisprudence (Fiqh), Hadith studies, and the scholarly understanding of Prophetic methodology throughout the Muslim world.
