The Shadhili Tariqa is a Sufi order of Sunni Islam founded by Abul Hasan Ali ash-Shadhili. Followers (Arabic murids, "seekers") of the Shadhiliya are known as Shadhilis.
It has historically been of importance and influence in North Africa and Egypt with many contributions to Islamic literature. Among the figures most known for their literary and intellectual contributions are Ibn 'Ata Allah, author of the Hikam, and Ahmad Zarruq, author of numerous commentaries and works, and Ahmad ibn Ajiba who also wrote numerous commentaries and works. In poetry expressing love of Muhammad, there have been the notable contributions of Muhammad al-Jazuli, author of the " Dala'il al-Khayrat", and Busiri, author of the famous poem, the Qaṣīda al-Burda. Many of the head lecturers of al-Azhar University in Cairo have also been followers of this tariqa.
Of the various branches of the Shadhili tariqa are the Fassiyatush, found largely in India, Sri Lanka and Pakistan. The Darqawi branch is found mostly in Morocco and the Darqawi Alawiyya (no connection to the " Kızılbaş- Turkish- Alevis" or " Syrian- Arab- Alawis") which originated in Algeria is now found the world over, particularly in Syria, Jordan, France and among many English-speaking communities. British scholar, Martin Lings wrote an extensive biography of the founder of this branch, Ahmad al-Alawi, entitled 'A Sufi Saint of the 20th century' (ISBN 0-946621-50-0)
The Swedish impressionist painter and Sufi scholar Ivan Aguéli (1869–1917) was the first official Moqaddam (representative) of the Shadhiliyya in Western Europe. Aguéli initiated René Guénon (1886–1951) into the Shadhili tariqa. 1 Guénon went on to write a number of influential books on tradition and modernity. 2 The anniversary urs of Hazrat Qutubul Akber Imam Nooruddin Abul Hasan Alee Ash Shadhili (Razi) is held on 12th Shawwal (the tenth month of lunar calendar) at Humaithara in Egypt.
