His writings, which dealt with various sciences and highlighted his skill and command over them, are clear. Among these scholars were two who were known for their opposition to blind imitation and their criticism of innovations and new occurrences. They were Abu Hamid al-Ghazali and Abu Bakr al-Tartushi. This is what benefited Ibn Tumart, giving him the ability to critique and instilling in him a spirit of revolt against stagnation and imitation, and a tendency to reject the apparent corruption that characterized the reality of Islamic life. Some of these scholars were prominent in theological disputes. Al-Tartushi has a book on this called "Al-Ta'liqa," and al-Ghazali has "Shifa' al-Mustarshidin," which is one of the finest books on this subject. This provided Ibn Tumart with an opportunity to become acquainted with various doctrines, to understand their arguments in interpretation, and to compare their issues and methodologies. This gave him breadth of intellectual horizon and liberation from narrow sectarianism. Al-Ghazali was known for his strong debating skills. It is enough to mention that he confronted and refuted the arguments of philosophers. Al-Ghazali was also one of the leaders in debate and argumentation. From them, Ibn Tumart learned the methods and etiquette of debate. There is no doubt that in Baghdad, he witnessed firsthand the extensive movement of dialogue that was taking place between doctrines and religions, which was particularly animated by those belonging to esoteric sects in their various forms. The prominent Ash'ari scholars, in particular, were engaged in establishing creed and refuting doubts raised against it. Thus, from these theoretical principles and etiquette, and from these practical observations, he developed a mastery of persuasion and refutation of opponents, which clearly appeared in his debates with jurists when he returned to the Maghreb.
