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).'"
