Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I participated with my uncles in the pact of «مطيبين» when I was a boy. Even now, I would not be willing to break such a covenant in exchange for red camels."
