Whakaotihia te rerenga e whai ake nei: Ko te tuatahi "Zawiya al-Fassiya" i whakatuhia e te tupuna o Abdelkader, a Abu al-Mahasin (i mate i te 1604), he tohunga Mahometa no Ksar el-Kebir me tetahi whanau bourgeois no Andalusi. I mua i tana taenga mai ki Fes, i whiwhi a Abu al-Mahasin i etahi manakohanga ki te Sultana Saadian a Ahmad al-Mansur whakawhetai ki nga toa i tukuna e ia ki te whawhai i te
Te Pakanga o Ksar el-Kebir (e mohiotia ana ko te Pakanga o nga Kingi e toru) i te 1578. I neke ia ki Fes i te 1580 ka tiimata te zawiya ma te whakaako i roto i tona ake whare i te takiwa o al-Mukhfiya (i te rohe Andalusiyyin o te taone nui), i tere whanake hei pokapū nui mo te karahipi i a ia ano. I hokona e Abu al-Mahasin nga whare tata ki te whakauru i tana whanui, a i te tau 1596 ka huri tetahi o nga whare hei whare karakia mo tana zawiya, ka tohua tana tama a Abu al-Abbas Ahmad al-Hafiz hei imam. Ko nga whakaakoranga a te zawiya i whai i te kura whakaaro o al-Jazuli (i roto i te raupapa Shadhili) me era o Abd al-Rahman al-Majdub (i mate i te 1569), he sheikh Sufi o mua i noho i Fes me te kaiwhakaako a Abu al-Mahasin.
