The Muwaṭṭa is an early collection of hadith comprising the subjects of Muslim law, compiled and edited by the Imam, Malik ibn Anas. Malik's best-known work, Al-Muwatta was the first legal work to incorporate and join hadith and fiqh together. The work was received with wide praise. Abu Bakr ibn al-`Arabi said: "The Muwatta’ is the first foundation and the core, while al-Bukhari’s book is the second foundation in this respect. Upon these two all the rest have built, such as Muslim and al-Tirmidhi."
