Also from Ibn Taymiyya’s The Madinan Way: The Soudness of the Basic Premises of the School of the People of Madina (page 26-27):
At-Tirmidhi and others related from the Prophet, may Allah bless him and grant him peace: “A time is soon coming when people will beat their camels in search of knowledge and will not find a man of knowledge than the man of Madina” It is related from more than one, and Ibn Jurayj, Ibn ‘Uyayna and other stated it refers to Malik.
…There is no doubt that there was no one in the time of Malik, to whom people drove their camels more than Malik…
…None of the Muslims dispute this and no one travelled to any of the men of knowledge of Madina as they travelled to Malik, neither before nor after him. People travelled to him from the east and the west, and people of different generations travelled to him. Among them were scholars, ascetics, kings and common people. His Muwatta’ spread throughout the land until there was no book after the Qur’an at the time known to have a greater dissemination than the Muwatta’.
