Abdallah ibn Yasin
Around 1040, Yahya ibn Ibrahim, a chieftain of the Gudala (and brother-in-law of the late Tarsina), went on pilgrimage to Mecca. On his return, he stopped by Kairouan in Ifriqiya, where he met Abu Imran al-Fasi, a native of Fes and a jurist and scholar of the Sunni Maliki school. At this time, Ifriqiya was in ferment. The Zirid ruler, al-Muizz ibn Badis, was openly contemplating breaking with his Shi'ite Fatimid overlords in Cairo, and the jurists of Kairouan were agitating for him to do so. Within this heady atmosphere, Yahya and Abu Imran fell into conversation on the state of the faith in their western homelands, and Yahya expressed his disappointment at the lack of religious education and negligence of Islamic law among his southern Sanhaja people. With Abu Imran's recommendation, Yahya ibn Ibrahim made his way to the "ribat" of Waggag ibn Zelu in the Sous valley of southern Morocco, to seek out a Maliki teacher for his people. Waggag assigned him one of his residents, Abdallah ibn Yasin.
