It is narrated from Sayyiduna Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever would like to recite the Qur'an fresh, just as it was revealed, let him recite it according to the recitation of Ibn Umm Abd (Abdullah bin Mas'ud)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

Zayd bin Wahb relates: I was sitting with Sayyiduna Umar (may Allah be pleased with him) when a thin, slender man (Abdullah bin Mas'ud) came. Umar (may Allah be pleased with him) looked at him, his face beaming with joy, and said: "A small vessel filled with knowledge, a small vessel filled with knowledge!" This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

Sayyiduna Ali (may Allah be pleased with him) was asked about the Companions of the Messenger of Allah (peace and blessings be upon him). He asked: About which of them? The people said: Tell us about Abdullah bin Mas'ud (may Allah be pleased with him). He said: "He learned the Book of Allah and the Sunnah, then he reached the utmost limit (of knowledge), and that is sufficient for his excellence." Then he mentioned the rest of the hadith. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) concerning this verse: "And do not drive away those who call upon their Lord morning and evening, seeking His Face" [Surah al-An'am: 52] , that it was revealed about five people of Quraysh, among whom were I and Ibn Mas'ud. Quraysh had said to the Prophet (peace and blessings be upon him): If you drive these people away from you, we will sit with you. Do you bring these people close to you in preference to us? So Allah Almighty revealed this verse: "And do not drive away those who call upon their Lord morning and evening" up to "the grateful" [Surah al-An'am: 52-53] . This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
