Musannaf Ibn Abi Shayba 34:273

Fadl narrated to us, Hashraj ibn Nabata narrated to us, he said: Sa'id ibn Jumhan narrated to me, he said: I said to Safina, "The Banu Umayya claim that the Caliphate is among them." He said: "The Banu al-Zarqa' have lied. Rather, they are kings from among the worst of kings, and the first of the kings is Mu'awiya."
