implicitly on his learning and adoption, as it was not prevalent among them, nor did the jurists focus on it in their studies of jurisprudence. When Ibn Tumart saw what jurisprudence had devolved into, especially during the Almoravid era, with its immersion in تقليد (taqlīd - imitation/following) and repetition, he intended to instill dynamism and vitality into it by promoting the spread of knowledge of the principles of jurisprudence (usul al-fiqh), which explain the foundations of Sharia and its rulings, and the methods of deriving them. His treatises on this matter were thus more introductory and stimulating than definitive or detailed on the issues. The reformist tendency in jurisprudence is evident in the educational aspect, represented by the selection of topics closely related to the spiritual dimension, such as prayer and jihad, to serve as an entry point. Once the soul adapts to them, it can accept the rest of the jurisprudential teachings in other areas. Perhaps the Mahdi intended to compose other treatises on the jurisprudence of transactions, but death overtook him before he could establish the society he aimed for with his call, a society that urgently needed the jurisprudence of transactions. Thus, the necessity of social reform required him to prioritize the educational aspects of jurisprudence. This tendency also appears in the presentation of jurisprudential issues coupled with their evidence from texts, a phenomenon that was absent among the jurists of the Maghreb. The Mahdi intended by this to establish a jurisprudence that originates from its principles and derives its rulings directly from them, which is an application of the aforementioned theoretical principles within the framework of reforming religious thought. The dominant tendency in Ibn Tumart's treatises is the principle of establishing roots (ta'sil), meaning referring the branches of jurisprudence back to their established principles from which they are derived. This was what constantly occupied his mind, and his theoretical statements, as well as his detailed partial rulings, flowed from it. Therefore, we will take this preoccupation as a fundamental focus for what we will present of Ibn Tumart's views in this chapter. The principle of establishing roots in Ibn Tumart: We have previously mentioned that the jurists of the Maghreb had an aversion to studying the principles.
