Musnad Abu Ya'la al-Mawsili 115:371

Ahmad narrated to us, Abu Dawud narrated to us, he said: Shu'bah and Hisham informed us, from Qatadah, that he heard Anas saying: The Messenger of Allah (peace be upon him) said: "There is no contagion and no evil omen." He then mentioned something similar to the hadith of Bahz, except that he said: "The *fa'l* (good omen) is the good word."
