Musnad Ahmad 32:2005

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