Philosophers, ancient or new? I was overcome by shyness and fear, so I began to make excuses and deny my engagement with the science of philosophy. The Commander of the Faithful understood my fear and shyness, so he began to speak about the question he had asked me, mentioning what Aristotle, Plato, and all the philosophers had said. He also presented the arguments of the Muslims against them. I saw in him a depth of memory that I did not imagine anyone engaged in this field, who was devoted to it, possessed.

What Ibn Rushd wrote as a summary and commentary on Aristotle's works was a result of Yusuf's interest in philosophy. He complained to Ibn Tufayl about the ambiguity of Aristotle's wording, or the wording of the translators from him. So Ibn Tufayl asked Ibn Rushd to summarize it and bring its purposes closer to people's understanding, excusing himself from the task by citing his old age and his preoccupation with serving the prince. The result of this was Ibn Rushd's commentaries on Aristotle: the Great, the Middle, and the Small, those that had a great impact on European philosophical thought in particular, and on philosophical thought in general.

When Abu Yusuf Ya'qub al-Mansur came, he initially followed his father's path in embracing philosophy and encouraging its scholars and bringing them closer to him. However, a state of aversion to this thought later befell him. He abandoned the sciences of philosophy and wrote to people in various lands to abandon these sciences altogether, and ordered their books to be burned, except for those related to medicine, arithmetic, and astronomy.

Ibn Rushd was banished from him due to accusations that reached him, showing his deviation from Sharia in parts of his philosophical writings. He was ordered to be expelled in a state of disgrace.

However, this crisis did not last long for Abu Ya'qub. He returned to his former relationship with philosophy and its scholars, and turned to learning it anew. He sent for Ibn Rushd from Al-Andalus to Marrakesh.
