These books include all the 6 authentic collection of Ahadith referred to in Arabic as "Al-Kutub Al-Sittah", which translates as"The Authentic Six". These six books are the works of6 Islamic scholars who, a few years after Prophet Muhammad's death collected "hadith" (the prophet's sayings and traditions) and painstakingly compiled the ones that they could attribute directly to Prophet Muhammad. After the Quran, these 6 books form the cornerstone of the Muslim (Sunni) faith and traditions as they provide a further elaboration of the Quran's sayings and commandments. Books that form part of the authentic six collection are the following:

1. Sahih Bukhari, collected by Imam Bukhari (d. 870), includes 7000+ ahadith

2. Sahih Muslim, collected by Muslim b. al-Hajjaj (d. 875), includes 9000+ ahadith

3. Sunan al-Nasa'i, collected by al-Nasa'i (d. 915)
