Musnad Abu Ya'la al-Mawsili 1:4

Al-Harith ibn Surayj Abu Umar narrated to us, Sufyan ibn Uyaynah narrated to us, Amr narrated to us, from Ibn Shihab, from Malik ibn Aws ibn al-Hadthan, that he narrated to him, saying: Umar sent for me after the day had advanced. I was granted permission, so I entered upon him while he was on a bed of palm fiber, his back leaning against its ropes, reclining on a leather pillow. He said to me: "O Malik, a group of your people has arrived, and I have ordered some wealth for them, so take it and distribute it among them." I said to him: "O Commander of the Faithful, I have no strength for that, so if you would order someone else to do it." He said: "Take it and distribute it among them." He said: Then Yarfa’ came to him and said: "O Commander of the Faithful, do you have any need for Uthman ibn Affan, Abd al-Rahman ibn Awf, al-Zubayr, and Sa’d?" He said: "Yes." So he granted them permission, and they entered. Then he came and said: "O Commander of the Faithful, do you have any need for Ali and al-Abbas?" He said: "Yes." He said: So they entered, and al-Abbas was saying: "O Commander of the Faithful, judge between me and this one." Sufyan said: And he mentioned harsh words. The people said: "O Commander of the Faithful, judge between them and relieve each one of them from the other." Umar said to them: "I adjure you by Allah, by Whose permission the heavens and the earth stand, do you know that the Messenger of Allah (peace and blessings of Allah be upon him) said: 'We are not inherited from; what we leave is charity'?" They said: "Yes." Umar said: "Indeed, Allah singled out His Messenger (peace and blessings of Allah be upon him) with a special matter that He did not single out anyone else with." Then he recited the verse: *'Whatever Allah restored to His Messenger from them—you did not spur for it any horses or camels'* (Al-Hashr: 6). Sufyan said: I do not know if he recited the verse after it or not. He said: "The Messenger of Allah (peace and blessings of Allah be upon him) distributed the wealth of Banu al-Nadir among you. By Allah, he did not prefer himself over you, nor did he withhold it from you. The Messenger of Allah (peace and blessings of Allah be upon him) would take from it his sustenance and the sustenance of his family for his year, and he would place what remained into the horses and weapons as equipment in the way of Allah." Then he said to them: "I adjure you by the One by Whose permission the heaven and the earth stand, do you know that?" They said: "Yes." Then he adjured Ali and al-Abbas with what he had adjured the people: "Do you both know that?" They said: "Yes." He said: "When the Messenger of Allah (peace and blessings of Allah be upon him) passed away, Abu Bakr was the successor of the Messenger of Allah (peace and blessings of Allah be upon him). You came, O Abbas, seeking your inheritance from your brother's son, and Ali came seeking the inheritance of his wife from her father. Abu Bakr said: The Messenger of Allah (peace and blessings of Allah be upon him) said: 'We are not inherited from; what we leave is charity.' You saw me—and Allah knows that he passed away righteous, rightly guided, and following the truth." "Then when Abu Bakr passed away, I said: I am the successor of the Messenger of Allah (peace and blessings of Allah be upon him) and the successor of Abu Bakr. You saw me—and Allah knows that I am truthful, righteous, rightly guided, and following the truth. You both came to me, and your matter was one, and you asked me to hand it over to you. I said: If you wish, I will hand it over to you on the condition that you have the covenant of Allah upon you that you will act therein as the Messenger of Allah (peace and blessings of Allah be upon him) used to act therein. So you took it on that basis." He said to them: "Is it not so?" They said: "Yes." He said: "Then you came to me to judge between you. By Allah, I will not judge between you with anything other than that until the Hour is established. If you are unable, then return it to me."
