 The Merinid Sultan, Abu al-Hassan then stripped them of these acquired advantages and gave them instead to the Berber Beni Iznassen tribe.Unhappy with this treatment, the Kharaj rebelled, killed the Merinid governor of the Saharan Ksours, Yahya ibn Al-iz, and escaped far eastwards to the remote desert in fear of the Sultan's retaliation.The second group of Beni Ubayd Allah - the Haraj - who lived west of Taourirt, subjugated themselves to the Merinids and remained their allies.
