In a treatise, a chapter was dedicated to explaining the Almoravids and describing their injustice and the deviation of their rule.

He titled a chapter in his treatise, "On the Almoravids," with the heading: "Stubbornness and Corruption on Earth."

Regarding these two aspects, and other errors and sins, we do not find detailed clarification from the Mahdi. If they are permissible for an Imam, or if he is infallible from them, then his infallibility is absolute. However, there is an ambiguous reference in the context of arguing for infallibility, which might be understood to mean he believes in infallibility from all sins. This is his statement: "And nothing repels evil except justice. And nothing repels sin except obedience."

The sin is not repelled. Its occurrence in the context of the two preceding analogies might suggest that the intention is directed towards sin in the realm of knowledge and principles that he conveys, and in the realm of governing people and managing their affairs. This excludes other forms of action from being a basis for infallibility.

If that is the case, what is the position of this infallibility that the Mahdi spoke of, in relation to the infallibility of the Shiites? It is clear that this infallibility is a lesser degree than the infallibility that the Shiites attribute to their Imams, which is characterized by comprehensiveness and absoluteness, as explained previously. Meanwhile, the Mahdi's infallibility is more likely to extend to some errors and sins outside the specified domains.

It appears that what Ibn Tumart believed about the infallibility of the Imam is merely an expression of the conditions stipulated by the Sunnis and Mu'tazilis for the Imam. However, it is an expression that has taken on an exaggerated form due to the harshness of the events surrounding Ibn Tumart in his call. This is also the case with many of his ideas related to the Imamate, especially. The following are the indications: Ibn Tumart, Treatise on the Explanation of the Sects of the Falsehoods: 90. Ibn Tumart, Book of the Imamate: 91.
