There is no way to knowledge except through transmission, and a mention of how the Shaykh al-Islam Ibn Taymiyyah (may Allah have mercy on him) received knowledge in the beginning of his pursuit.

The Shaykh : And the scholars have no way to acquire knowledge except through the path of transmission, the transmission of the later generations from the earlier ones; that the student takes from his shaykh, and that the seeker takes from the books of those who preceded him among the people of knowledge, so that he may increase in knowledge upon knowledge.
It is apparent that the Shaykh al-Islam Ibn Taymiyyah (may Allah have mercy on him) did not receive knowledge immediately upon beginning his pursuit of knowledge, and this is a natural matter. The book *Ihya' 'Ulum al-Din* contains what it contains of weak and fabricated hadiths, so he studied this book, and he had a remarkable and very remarkable memory, so the memorized content of this book became firmly established in his memory. Then, when he was asked about an issue, he would elaborate in his answer by citing verses and hadiths. Then, over time, he began to purify his information, whether in terms of narration or understanding. We find in some of his books traces of his early study, where he was still in the pursuit of knowledge. It appears that this addition in this hadith was received by him from *Ihya'* or from other books like *Ihya'* that contain hadiths of every kind. As it was said about *Ihya'*, we say, a fortiori, about the Shaykh al-Islam Ibn Taymiyyah: he took it and did not fabricate it. But Allah (Mighty and Majestic) bestowed upon the Shaykh al-Islam correct knowledge afterwards, until he became a reference in that, particularly in the science of hadith, to the extent that al-Hafiz al-Dhahabi exaggerated and said: "Every hadith that Ibn Taymiyyah does not know is not a hadith." We believe that there is some exaggeration in this, but when scholars want to display the rank of a scholar in a certain science, especially if he is wronged like the Shaykh al-Islam Ibn Taymiyyah, whose rights are suppressed, they say such things: "Every hadith that Ibn Taymiyyah does not know is not a hadith."
Thus, the sufficiency mentioned in these two hadiths is what is sufficient for a person, neither less than his need nor more; this is the middle, and the best of matters are their middles.
