Musnad Ahmad 28:560

Ya'qub narrated to us, my father narrated to us, from Ibn Ishaq, Abu Ubaydah bin Muhammad bin Ammar bin Yasir narrated to me, from Miqsam Abu al-Qasim, the freed slave of Abdullah bin al-Harith bin Nawfal, who said: I went out with Talid bin Kilab al-Laythi until we came to Abdullah bin Amr bin al-As while he was circumambulating the House, holding his sandals in his hand. We said to him: "Were you present with the Messenger of Allah, may Allah bless him and grant him peace, when the Tamimi spoke to him on the day of Hunayn?" He said: "Yes. A man from Banu Tamim, called Dhu al-Khuwaysirah, came forward and stood before the Messenger of Allah, may Allah bless him and grant him peace, while he was giving to the people. He said: 'O Muhammad, I have seen what you have done this day.' The Messenger of Allah, may Allah bless him and grant him peace, said: 'Yes, and how did you see it?' He said: 'I did not see you act justly.' He said: The Messenger of Allah, may Allah bless him and grant him peace, became angry, then said: 'Woe to you! If justice is not with me, then with whom is it?' Umar bin al-Khattab said: 'O Messenger of Allah, shall we not kill him?' He said: 'No, leave him, for he will have followers who will delve deep into the religion until they exit from it, just as an arrow exits from the game. One looks at the arrowhead and finds nothing, then at the shaft and finds nothing, then at the notch and finds nothing; it has preceded the dung and the blood.'" Abu Abd al-Rahman [who is Abdullah bin Ahmad] said: "This Abu Ubaydah, his name is Muhammad, and he is trustworthy. His brother, Salamah bin Muhammad bin Ammar, no one narrated from him except Ali bin Zayd, and we do not know his status. As for Miqsam, there is no harm in him. This hadith has other chains with this meaning, and other authentic chains with this meaning, and Allah, Glory be to Him and Exalted is He, knows best."
