Musannaf Ibn Abi Shayba 21:481

Muhammad ibn Fudayl narrated to us, from Layth, from Mujahid, from Yuthay', from Ka'b, who said: "Were it not for words that I say, the Jews would have turned me into one braying with the braying donkeys and howling with the howling dogs: 'I seek refuge in Your Noble Face, and in Your Great Name, and in Your Perfect Words—which neither the righteous nor the wicked can surpass—the One who does not betray His neighbor, from the evil of what descends from the heaven and what ascends into it, and from the evil of what He created, scattered, and brought into being.'"
