Sahih Muslim by Imam Muslim
Sahih Muslim (full title Al-Musnadu Al-Sahihu bi Naklil Adli) is one of the Kutub al-Sittah (six major ahadith) of the hadith in Islam. It is the second most authentic hadith collection after Sahih al-Bukhari, and is highly acclaimed by all Muslims. It was collected by Muslim ibn al-Hajjaj, also known as Imam Muslim.
Many Muslims regard this collection as the second most authentic of the six major hadith collections, containing only sahih hadith, an honor it shares only with Sahih al-Bukhari, both being referred to as the Two Sahihs. Sahihs translates as authentic or correct.
