Abdallah ibn Yasin
The name "Almoravid" was tied to a school of Malikite law called "Dar al-Murabitin" founded in Sus al-Aksa, modern day Morocco, by a scholar named Waggag Ibn Zallu. Ibn Zallu sent his student Abdallah ibn Yasin to preach Malikite Islam to the Sanhaja Berbers of the Sous and Adrar (present-day Mauritania). Hence, the name of the Almoravids comes from the followers of the Dar al-Murabitin, "the house of those who were bound together in the cause of God."
