Sayyiduna Abdul Rahman bin Awf (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "I was present with my paternal uncles at the alliance of al-Mutayyabin (the Perfumed Ones), and I was a boy in those days. I would not like to break that alliance, even if I were to be given red camels in exchange for it." Al-Zuhri said: The Prophet (peace and blessings be upon him) said: "Whatever alliance Islam finds, it only increases its strength; however, there is no alliance in Islam." The narrator says: The Prophet (peace and blessings be upon him) had established affection between Quraysh and the Ansar.
Imam Ahmad, Imam Abu Ya'la and Imam al-Bazzar recorded it. The narrators of the hadith of Sayyiduna Abdul Rahman bin Awf (may Allah be pleased with him) are the narrators of the Sahih, and the same is true of the mursal report of al-Zuhri.
