Musnad Ahmad 32:835

Bahz narrated to us, Shu'bah narrated to us, Qatadah informed me that he heard Anas say: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no contagion and no superstition." He said: "And the good omen pleases me." I said: "What is the good omen?" He said: "The good word."
