Amr bin Maymun relates that a whole year would pass over Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) without his narrating any hadith from the Messenger of Allah (peace and blessings be upon him). Then one day he narrated a hadith on the authority of the Messenger of Allah (peace and blessings be upon him), and a state of sorrow and awe came over him, sweat began to drip from his forehead, and he began to say (out of utmost caution): "The Messenger of Allah (peace and blessings be upon him) said it like this, or something close to this." 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 al-Aswad that he heard Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) say: "My brother and I came from Yemen (to Madinah), and for a long time we kept thinking that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) was a member of the household of the Messenger of Allah (peace and blessings be upon him), because we frequently saw him and his mother going in and out of the house of the Messenger of Allah (peace and blessings be upon him) without restriction." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

Shaqiq relates: I heard Sayyiduna Hudhayfah (may Allah be pleased with him) say: "In his habits and manners, his bearing and his ways, Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) was the most similar of people to the Messenger of Allah (peace and blessings be upon him), from the time he left his house until he returned (he was an embodied model of the Sunnah). I do not know what his affairs inside his house were like. However, the well-informed Companions of the Messenger of Allah (peace and blessings be upon him) know that Ibn Umm Abd (Abdullah bin Mas'ud) will be among the closest to Allah on the Day of Resurrection." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

Awn bin Abdullah bin Utbah narrates from his father that the state of worship of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) was such that when all eyes had gone to sleep, a sound like the humming of bees (of recitation and weeping) would be heard from him until the morning.

Jami' bin Shaddad relates: I heard Abdullah bin Mirdas say: "Every Thursday Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) would stand and deliver a sermon to us. He would speak such brief and comprehensive words that we would wish he would lengthen his talk further."

Habbah al-Urani relates: I read the letter of Sayyiduna Umar (may Allah be pleased with him) to the people of Kufah, in which was written: "After praise and glorification: indeed you are the chiefs of the Arabs and their head. You are my arrow which I shoot (at the enemies), from whichever direction they come. I have sent Sayyiduna Abdullah bin Mas'ud to you and have chosen him for you, and in his matter I have preferred you over myself."

It is narrated from Habbah al-Urani that some people came to Sayyiduna Ali (may Allah be pleased with him) and praised Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him). Upon this Sayyiduna Ali (may Allah be pleased with him) said: "I say about him the same as what these people said, and even better: he read the Qur'an, held its lawful to be lawful and its unlawful to be unlawful; he is a jurist in the religion and a scholar of the Sunnah."

It is narrated from Sayyiduna Abu Mas'ud Uqbah bin Amr (may Allah be pleased with him) that he said: In my view there is no one more knowledgeable of what Allah Almighty revealed to Muhammad (peace and blessings be upon him) than Abdullah bin Mas'ud (may Allah be pleased with him). Then Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) said: "If you say that, then indeed he used to hear (the words of the Prophet) when we did not hear, and he used to enter (into the presence of the Prophet (peace and blessings be upon him)) when we were not permitted to enter."

Ibrahim al-Taymi narrates from his father that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said (out of utmost humility): "If you knew my sins, not even two men would walk behind me, and you would throw dust on my head. And indeed I wish that Allah Almighty would forgive me a single one of my sins, even if (in exchange) I were called 'Abdullah bin Rawthah (son of dung).'"

It is narrated from Alqamah: I came to Syria and prayed two rak'ahs, then I supplicated: "O Allah, grant me a righteous companion." I met some people and sat with them. Suddenly a man came and sat beside me. I asked: Who is this? The people said: This is Sayyiduna Abu al-Darda (may Allah be pleased with him). I said to him: I had prayed to Allah to grant me a righteous companion, and He has granted me you. He asked: Where are you from? I said: From the people of Kufah. He said: "Is there not among you Ibn Umm Abd (Sayyiduna Ibn Mas'ud), who was the keeper of the sandals, the pillow and the ablution vessel of the Messenger of Allah (peace and blessings be upon him)? And is there not among you the man (Sayyiduna Ammar) whom Allah protected from Satan by the blessed tongue of His Prophet? And is there not among you the confidant of the Messenger of Allah (peace and blessings be upon him) (Sayyiduna Hudhayfah), whose secret no one knows besides him?" This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. All the chains before it are also sahih, but the two Shaykhs did not record them; I did not comment on them because they were not musnad (connected to the Prophet), whereas this report is musnad.
