Malik ibn Anas in the context of "Six major hadith collections"

Kutub al-Sittah (Arabic: ٱلْكُتُب ٱلسِّتَّة, romanized: al-Kutub al-Sitta, lit. 'the Six Books'), also known as al-Sihah al-Sitta (Arabic: الصحاح الستة, romanized: al-Ṣiḥāḥ al-Sitta, lit. 'the Authentic Six') are the six canonical hadith collections of Sunni Islam. They were all compiled in the 9th and early 10th centuries, roughly from 840 to 912 CE and are thought to embody the Sunnah of Muhammad.

The books are the Sahih of al-Bukhari (d. 870), the Sahih of Muslim ibn al-Hajjaj (d. 875), the Sunan of Abu Dawud (d. 889), the Sunan of al-Tirmidhi (d. 892), the Sunan of al-Nasa'i (d. 915), and the Sunan of Ibn Majah (d. 887 or 889) as the sixth book, though some (particularly the Malikis and Ibn al-Athir) instead listed the Muwatta of Malik ibn Anas (d. 795) as the sixth book, and other scholars list Sunan of al-Daraqutni (d. 995) as the sixth book. Sunan ibn Majah largely won out as the sixth canonical book because its content has less overlap with the other five compared with its two contenders.

The Maliki school or Malikism is one of the four major schools of Islamic jurisprudence within Sunni Islam. It was founded by Malik ibn Anas (c. 711–795 CE) in the 8th century. In contrast to the Ahl al-Hadith and Ahl al-Ra'y schools of thought, the Maliki school takes a unique position known as Ahl al-Amal, in which they consider the Sunnah to be primarily sourced from the practice of the people of Medina and living Islamic traditions for their rulings on Islamic law.

The Maliki school is one of the largest groups of Sunni Muslims, comparable to the Shafi’i madhhab in adherents, but smaller than the Hanafi madhhab. Sharia based on Maliki Fiqh is predominantly found in North Africa (excluding parts of Egypt), West Africa, Chad, Sudan and the Persian Gulf.

Ja'far ibn Muhammad al-Sadiq (Arabic: جعفر ابن محمد الصادق, romanized: Jaʿfar ibn Muḥammad al-Ṣādiq; c. 702–765) was a Muslim scholar, jurist, hadith transmitter and the sixth and last agreed-upon Shia Imam amongst Twelvers and Isma'ilis. Known by the title al-Sadiq ("The Truthful"), Ja'far was the eponymous founder of the Ja'fari school of Islamic jurisprudence. In the canonical Twelver hadith collections, more traditions are cited from Ja'far than that of the other Imams combined, although their attribution to him is questionable, making it hard to determine his actual teachings. Among the theological contributions ascribed to him are the doctrine of nass (divinely inspired designation of each Imam by the previous Imam) and isma (the infallibility of the Imams), as well as that of taqiya (religious dissimulation under persecution).

Al-Sadiq is also revered by Sunni Muslims as a reliable transmitter of hadith, and a teacher to the Sunni scholars Abu Hanifa and Malik ibn Anas, the namesakes of the Hanafi and Maliki schools of jurisprudence. Al-Sadiq also figures prominently in the initiatic chains of many Sufi orders. A wide range of religious and scientific works were attributed to him, though no works penned by al-Sadiq remain extant.

The Maliki school or Malikism is one of the four major schools of Islamic jurisprudence within Sunni Islam. It was founded by Malik ibn Anas (c. 711–795 CE) in the 8th century. In contrast to the Ahl al-Hadith and Ahl al-Ra'y schools of thought, the Maliki school takes a unique position known as Ahl al-A'mal, in which they consider the Sunnah to be primarily sourced from the practice of the people of Medina and living Islamic traditions for their rulings on Islamic law.

Al-Muwaṭṭaʾ (Arabic: الموطأ, 'the well-trodden path') or Muwatta Imam Malik (Arabic: موطأ الإمام مالك) of Imam Malik (711–795) written in the 8th-century, is one of the earliest collections of hadith texts comprising the subjects of Islamic law, compiled by the Imam, Malik ibn Anas. It is also the earliest extant example of a musannaf, referring to a genre of hadith compilation which arranges hadith topically.

Malik's best-known work, Al-Muwatta was the first legal work to incorporate and combine hadith and fiqh.
