مسلم بن الحجاج
Out of 300,000 hadith which he evaluated, approximately 12,000 were extracted for inclusion into his collection based on stringent acceptance criteria. Each report in his collection was checked and the veracity of the chain of reporters was painstakingly established. Sunni Muslims consider it the second most authentic hadith collection, after Sahih al-Bukhari. "Sahih Muslim" is divided into 43 books, containing a total of 9200 narrations. However, it is important to realize that Muslim ibn al-Hajjaj never claimed to collect all authentic traditions as his goal was to collect only traditions that all Muslims should agree on about accuracy.
