The Sanhaja were at this stage only superficially Islamicised and still clung to many heathen practices, and so Ibn Yasin preached to them an orthodox Sunnism.
Ibn Yasin introduced his orthodox rule - amongst other things wine and music were forbidden, non-Islamic taxes were abolished and one fifth of the spoils of war were allocated to the religious experts.
