It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them both) gave him the glad tidings that the Noble Prophet (peace and blessings be upon him) said: Whoever wishes to recite the Qur'an as fresh as it was revealed, then let him recite according to the recitation of the son of Umm 'Abd (Abdullah bin Mas'ud, may Allah be pleased with him).

Sayyiduna Umar bin Khattab (may Allah be pleased with him) narrated a similar hadith of the Prophet, however, in it are the words "ghaddan aw ratban."

Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Whoever wants to recite the Qur'an fresh as it was revealed, then he should recite according to the recitation of Ibn Umm Abd, that is, Abdullah bin Mas'ud (may Allah be pleased with him).

Masruq (may Allah have mercy on him) says: I was sitting with Sayyiduna Abdullah bin Amr bin Aas (may Allah be pleased with them), and the mention of Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) came up. He said: I have loved this man ever since I heard this hadith from the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) said: Learn the Qur’an from these four persons: Ibn Umm Abd, Mu’adh, the freed slave of Abu Hudhaifah, Salim. He (peace and blessings be upon him) mentioned Ibn Umm Abd, that is, Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him), first. Ya’la, the narrator, says: I forgot the name of the fourth.

Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: Learn the Qur'an from these four individuals: Abdullah bin Mas'ud, Salim the freed slave of Abu Hudhaifah, Mu'adh bin Jabal, and Ubayy bin Ka'b (may Allah be pleased with them).

Sayyiduna Anas (may Allah be pleased with him) narrates that during the blessed era of the Noble Prophet (peace and blessings be upon him), four individuals had memorized the entire Qur’an; all of them were from among the Ansar: Ubayy ibn Ka’b, Mu’adh ibn Jabal, Zayd ibn Thabit, and Abu Zayd.
