Yahya Ibn Ibrahim (Arabic: يحيى بن إبراهيم الجدالي) (c. 1048)[1] was a leader of the Godala tribe in the Adrar plateau modern day Mauritania.
These tribes rose to proclaim the truth, to repel injustice and to abolish all non-canonical taxes (magharim).
Abdallah ibn Yasin began to call people to Jihad and made them proclaim the truth.
[1] As described by Al-Bakri Yahya Ibn Ibrahim went on the Hajj to Mecca and during his return journey met a jurist (Abu Imran al-Fasi).
Al-Fasi found Ibrahim "wholly ignorant, though avid to learn, full of good intentions and firm of faith" [1] From Al-Bakri: What prevents you from studying the religious law properly, and from ordering good and prohibiting evil?"
