A strong unified state in the far west of the Islamic world, and he continued to carry out his message until his martyrdom in one of the battles with those who left the religion.After that, the Maliki jurists inherited the religious and spiritual authority, which was a source of strength and support for the rulers of the Almoravids state, so that any prince among them would not cut off an order without consulting the jurists and obtaining their approval, and the situation continued in this form of friendliness and agreement between the prince and his entourage of jurists until the end of the state era.
