al-Warjilani
?–c. 1175 CE · Tunis
Abu Ya'qub Yusuf ibn Ibrahim al-Sadrati al-Warjilani was a Maghribi scholar of the Ibadi branch of Islam — a tradition, distinct from both Sunni and Shia, that traces itself to the early Kharijite movement and survives today mainly in the Mzab valley of Algeria, on the island of Jerba (Tunisia), and in Oman. His nisba (the place-name attached to his name) points to Warjalan (Wargla) and the nearby town of Sadrata, oasis settlements in the Algerian Sahara that were then centres of Ibadi learning. Sources place his death around 570 AH (1175 CE); the date is a traditional estimate and is marked "circa." His birth date is not recorded.
He is remembered for two achievements. First, he composed al-Dalil wa'l-burhan ("The Guide and the Proof"), a work of kalam (rational theology) that systematically set out Ibadi positions on faith, grave sin, the divine attributes, and the vision of God; later writers admired it and compared it to the great Sunni theologians al-Ghazali and al-Baqillani. Second, he is traditionally credited with arranging and supplementing the hadith collection attributed to al-Rabi' ibn Habib, producing the ordered recension that Ibadis call Tartib al-Musnad — for them the foremost collection of Prophetic reports. He is also assigned a theological-juridical synthesis, al-Mujaz. Reports that he studied in Tunis before returning home, and later traditions of travel further afield, are part of the biographical record but are not uniformly attested.

What they did here
Reference works report that he studied in Tunis before returning to Warjalan, where he is said to have stimulated an Ibadi intellectual revival that drew students from across the Maghrib, especially Jerba. Reported in the biographical tradition rather than firmly dated.
About Tunis
Tunis in the medieval and early modern periods was a flourishing North African port city ruled successively by Arab dynasties, then the Ottoman Empire from the sixteenth century onward, its whitewashed medina rising behind harbor walls where ships from across the Mediterranean brought spices, silks, and scholars. The city enjoyed a mild climate tempered by sea breezes, though summers burned fierce and water was precious—a reality that shaped both daily life and the careful layout of its fountains and hammams. The Jewish community of Tunis was one of North Africa's most vital, numbering in the thousands by the medieval period and concentrated in their own quarters, where they maintained Hebrew schools, courts applying rabbinic law, and a thriving textile and banking trade that made them indispensable to the city's economy despite periodic restrictions and taxes imposed by Muslim rulers. For centuries, Tunis was a beacon of Jewish learning and piety, a place where traditions from Spain mixed with the customs of North Africa to create a distinctive Mediterranean Jewish culture. The Great Synagogue of Tunis, rebuilt several times over the centuries, stood as a symbol of communal endurance—a place where worshippers gathered not only for prayer but for the transmission of texts, responsa, and the living memory of Jewish law that sustained diaspora life far from the land of Israel.
