عبد الله بن ياسين
After receiving a letter for his former teacher Abu Imran al-Fasi asking him to help teach religion to the southern Sanhaja Saharan tribes, he chose Abdallah ibn Yasin, to accompany the Gudala leader Yahya ibn Ibrahim to the Sahara. Waggag Ibn Zallu then became the spiritual guide of the Almoravid's first leader.
