Volume 5, Book 57, Number 104:
Narrated ‘Abdullah bin ‘Amr:
Allah’s Apostle neither talked in an insulting manner nor did he ever speak evil intentionally. He
used to say, “The most beloved to me amongst you is the one who has the best character and man –
ners.” He added, ” Learn the Qur’an from (any of these) four persons. ‘Abdullah bin Mas’ud, Salim the
freed slave of Abu Hudhaifa, Ubai bin Ka’b, and Mu’adh bin Jabal.”
