Ibn Shihab (may Allah have mercy on him) said: Malik bin Aws bin al-Hadathan al-Nasri (may Allah be pleased with him) informed me, and Muhammad bin Jubayr bin Mut'im (may Allah have mercy on him) had mentioned to me part of this hadith of his. So I went and entered upon Malik bin Aws bin al-Hadathan (may Allah be pleased with him). I asked him about that hadith, and Malik (may Allah be pleased with him) said: I was among my family when the day had well advanced, and suddenly the messenger of Umar (may Allah be pleased with him) came and said: "The Commander of the Faithful is calling for you." I went with him to Umar (may Allah be pleased with him). He was sitting on a bed woven of palm leaves, with no bedding on it, and there was a pillow made of leather. I greeted him and sat down. He said: "O Malik! Sit here."
"Some households of your people have come, and I have ordered (something of wealth) for them; divide it among them." I said: O Commander of the Faithful! Order someone other than me to do it. He said: "O man! Take it." We were sitting with him when the doorkeeper came, asking permission for Uthman, Abd al-Rahman, al-Zubayr and Sa'd (may Allah be pleased with them). Umar (may Allah be pleased with him) gave permission. Having been given permission, they entered and greeted. After a little while the doorkeeper came again and said to Umar (may Allah be pleased with him): Ali and al-Abbas (may Allah be pleased with them both) are asking permission. He said: "Give them permission." The two entered, greeted and sat down, and al-Abbas (may Allah be pleased with him) said: "Judge between me and this man." The group, that is, Uthman and his companions, said: O Commander of the Faithful! Judge between the two of them and give each of them relief from the other.
