From Sahih Muslim (Hadith 6338):
Masruq reported:They made a mention of Ibn Mas'ud before 'Abdullah b. Amr, whereupon he said: He is a person whose love is always fresh in my heart after I heard Allah's Messenger (ﷺ) as saying: Learn the recita- tion of the Qur'an from four persons: from Ibn Mas'ud, Salim, the ally of Abu Hudhaifa, Ubayy b. Ka'b, Mu'adh b. Jabal
