Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "I was present at the pact of Banu Hashim, Banu Zuhrah and Banu Taym, and I would not like to break that pact even if I were given red camels in exchange for it. If I were called to it even today, I would respond, on the condition that good is enjoined, evil is forbidden, and the right of the oppressed is taken from the oppressor."
Al-Bazzar recorded it; its chain contains Dirar bin Surad, who is da'if (weak), and the narration has another route as well.
