Musnad Ahmad 482:154

Yahya ibn Ishaq narrated to us, Ibn Lahi'ah informed us, from al-Harith ibn Yazid, from Ali ibn Rabah, from Uqbah ibn Amir al-Juhani, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "These lineages of yours are not a cause of revilement against anyone. You are all the children of Adam. You are like the rim of a measuring vessel that you have not filled. No one has superiority over another except through religion or piety. It is sufficient for a man to be foul-mouthed, stingy, and obscene."
