Abu Madyan Shu'ayb ibn al-Husayn al-Ansari, 1115/16-1198, poet, teacher and Sufi mystic, was born in the town of Cantillana near Seville in Muslim Spain and is buried at al-Ubbad outside the city of Tlemcen in Western Algeria. After spending many years of his life learning from the most famous Sufis of Morocco, he settled in the Algerian city of Bijaya, where he spread his particular brand of orthodox mysticism to Sufi adepts and the general public alike. Called 'Shaykh of Shaykhs' and 'the Nurturer', al-Ghawth, by his contemporaries, Abu Madyan was the most influential Sufi of the formative period of mysticism in North Africa and had a profound influence on the eventual Qadiri and Shadhili Sufi traditions.
