Sahih Muslim (Ṣaḥīḥ Muslim) is a collection of hadith compiled by Imam Muslim ibn al-Hajjaj al-Qushayri al-Naysaburi (rahimahullah). His collection is considered to be one of the most authentic collections of the Sunnah of the Prophet Muhammad (SAW), and along with Sahih al-Bukhari forms the "Sahihain," or the "Two Sahihs."
