The Kutub al-Sittah are six books containing collections of hadith compiled by six Sunni Muslim scholars in the ninth centuryCE, approximately two centuries after the death of Muhammad. They are sometimes referred to as al-Sihah al-Sittah, which translates as "The Authentic Six". They were first formally grouped and defined by Ibn al-Qaisarani in the 11th century, who add Sunan ibn Majah to the list. Since then, they have enjoyed near-universal acceptance as part of the official canon of Sunni Islam. Not all Sunni Muslim jurisprudence scholars agree on the addition of Ibn Majah. In particular, the Malikis and Ibn al-Athir consider al-Mawatta' to be the sixth book. The reason for the addition of Ibn Majah's Sunan is that it contains many Hadiths which do not figure in the other five, whereas all the Hadiths in the Muwatta' figure in the other Sahih books.
Significance
s view the six major hadith collections as their most important, though the order of authenticity varies between Madhhabs:
Sahih Muslim, collected by Muslim b. al-Hajjaj, includes 7,500 ahadith
Sunan al-Sughra, collected by al-Nasa'i, includes 5,270 ahadith
Sunan Abu Dawood, collected by Abu Dawood, includes 5,274 ahadith
Jami al-Tirmidhi, collected by al-Tirmidhi, includes 4,400 ahadith
Either:
Sunan ibn Majah, collected by Ibn Majah, includes 4,341 ahadith
Muwatta Malik, collected by Imam Malik, 1,720 ahadith
The first two, commonly referred to as the Two Sahihs as an indication of their authenticity, contain approximately seven thousand hadiths altogether if repetitions are not counted, according to Ibn Hajar.
Authors
According to the CambridgeHistory of Iran: "After this period commences the age of the authors of the six canonical collections of Sunni hadith, all of whom were Persian, except Imam Malik. The authors of the six collections are as follows:
Muhammad b. Isma'il al-Bukhari, the author of the Sahih Bukhari, which he composed over a period of sixteen years. Traditional sources quote Bukhari as saying that he did not record any hadith before performing ablution and praying. Bukhari died near Samarqand in 256/869–70
Muslim b. Hajjaj al-Naishapuri, who died in Nishapur in 261/874–5 and whose Sahih Muslim is second in authenticity only to that of Bukhari. Some scholars rate the authenticity of Sahih Muslim more than Sahih Bukhari
Abu Dawood Sulaiman b. Ash'ath al-Sijistani, a Persian but of Arab descent, who died in 275/888–9.
Muhammad b. 'Isa al-Tirmidhi, the author of the well-known as Sunan al-Tirmidhi, who was a student of Bukhari and died in 279/892–3.
Abu 'Abd al-Rahman al-Nasa'i, who was from Khurasan and died in 303/915–16.
