Mishkat al-Masabih 246

Abu Huraira transmitted [from the Prophet], "The time is approaching when men will urge on their camels in search of knowledge, but will find no one more learned than the learned man of Medina.” Tirmidhi transmitted it. and in his Jami' he quotes Ibn ‘Uyaina as saying that Malik b. Anas was meant, and the same view is expressed by ‘Abd ar-Razzaq. Ishab b. Musa said he heard Ibn ‘Uyaina say that he was al-‘Umari the ascetic, whose name was ‘Abd al-‘Aziz b. ‘Abdallah.
