عبد الله بن ياسين
The name might be related to the "ribat" of Waggag ibn Zallu in the village of Aglu (near present-day Tiznit), where the future Almoravid spiritual leader Abdallah ibn Yasin got his initial training. The 13th-century Moroccan biographer Ibn al-Zayyat al-Tadili, and Qadi Ayyad before him in the 12th century, note that Waggag's learning center was called "Dar al-Murabitin" (The house of the Almoravids), and that might have inspired Ibn Yasin's choice of name for the movement.
