Abu 'Abdallah Muhammad b. Sulayman al-Jazuli was a Sharif associated with the Shadhiliyya and the founder of its Jazuliyya branch. His religious influence was particularly strong in southern Morocco, the Sus, and neighbouring regions. He claimed descent from the Prophet, a status that later gave his memory special importance in the political mobilization of Sharifian forces.

Al-Jazuli’s principal work, Dala'il al-Khayrat, was a collection of prayers for the Prophet. He also established new zawiyas, especially in southern Morocco, helping create a broad network of Shadhiliyya institutions. During the fifteenth-century weakening of central authority, this network acquired a political role and participated in the religious agitation directed against the last Marinid sultan, 'Abd al-Haqq.

Al-Jazuli died in 1465, and rumours circulated that 'Abd al-Haqq had ordered his poisoning. The alleged martyrdom amplified his influence after death. His disciples, led in part by 'Umar b. Sulayman al-Shayazmi, carried his body through campaigns in the Sus before it was buried at Afughal, where the tomb became a source of prestige for the later Sharifian dynasty.
