His doctrine was for the Berbers due to the general lack of fluency in the Arabic language and its laws: ... and the five prayers are also taken.

A prominent position in this classification, as a branch of the third section is allocated to it. Ibn Al-Qurtubi, in accounting, considered it a major principle in religion. Ibn Tumart gave all this status by saying: .

It is clear that the Mahdi did not base his classification on a review of the reality of the sciences in his time, as Ibn al-Nadīm did. Rather, he started from a mental image that defined what is obligatory for a Muslim to do according to his opinion. Thus, the subjective factor was reflected in the classification, and it lacked the objectivity that requires a broader enumeration, especially for those sciences that are not far removed from religious sciences. It seems that the man's limited culture in natural sciences and philosophy played a role in this.

We can finally say that the general structure of Ibn Tumart's classification of sciences is a novel structure, free from previous examples. He derived it from the specificity of his authentic Islamic culture. However, starting from an evaluative perspective of what a Muslim should learn, alongside cultural limitations in worldly sciences, made this classification closer to a curriculum than a classification of sciences.

Methods of Knowledge: 11 Ibn Tumart definitively states that there are only three methods of knowledge: reason, hearing, and senses. He emphasizes that "this is an exhaustive division that encompasses humankind in this world and the hereafter."

With this emphasis, he seems to be responding to those who took illumination as a path to knowledge, including his teacher Al-Ghazali.

He supported this exclusivity with an indirect textual proof, which is that man will not be questioned on the Day of Resurrection except about what his hearing, his sight, and his heart brought him, as indicated by the Almighty's saying: "Indeed, the hearing, the sight, and the heart – all of those will be [questioned] about it."
