Masruq reports: We were present with Sayyiduna Abdullah bin Amr (may Allah be pleased with him). We mentioned a hadith regarding Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), so he said: He is a person whom I have loved since the day I heard the Messenger of Allah (peace and blessings be upon him) say—I heard the Messenger of Allah (peace and blessings be upon him) say: "Learn the recitation of the Qur'an from four people: Ibn Umm Abd (that is, Abdullah bin Mas'ud), Ubayy bin Ka'b, Salim the freed slave of Abu Hudhayfah, and Mu'adh bin Jabal."
