Ibn Khallikan and Ibn al-Athir. Al-Tartushi was a jurist, deeply versed in Sharia politics, on which he wrote his book "Siraj al-Muluk" (The Lamp of Kings). He was also a rebel against heresy, and wrote "Al-Hawadith wal-Bid'ah" (Events and Heresies). He also has an abridgement of "Tafsir al-Tha'alibi" (The Exegesis of al-Tha'alibi).

Abu Abdullah Muhammad bin Mansur al-Hadrami: He is the one to whom al-Mahdi read Al-Muwatta and narrated it from him, as stated in the chain of narration. The author of "Al-Hullal al-Mawshiyah" mentioned that he read to him, but we have not found a biography for him.

These renowned scholars, and others whose names have not been preserved for us, received knowledge.

Ibn Tumart received knowledge in its various branches for ten years. When he felt he had achieved what he aspired to, he began his journey back to the Maghreb, with images of the negative aspects of his people's political and social life forming in his mind.

The Journey of Return: The journey back to the Maghreb was not an ordinary journey for Ibn Tumart, unlike those taken by most pilgrims and students of knowledge from the Maghreb eager to return to their homelands and families.

Rather, it was a journey of serious work that he did not abandon in any city or village he passed through. The abundant theoretical knowledge he received from his sheikhs did not remain a mere image in his mind, but rather stirred in him the motives for action. He committed himself on the path of da'wah (invitation to Islam) to spread knowledge so that ignorance of religion would be lifted, and to enjoin good and forbid evil so that Sharia would be realized in the reality of life.

This journey was an important opportunity for Ibn Tumart to put his scientific and rhetorical talents to the test. From the moment he set out until his arrival, he spread knowledge among the people whenever the opportunity arose, and changed evil among the commoners and the princes alike. He was not deterred by the traveler's haste to return home, nor by the fear of changing evil due to a sense of alienation and loss of support from family and kin.
