Musnad Ahmad 32:622

'Abd al-Wahhab narrated to us, Hisham informed us, from Qatadah, from Anas ibn Malik, that the Prophet of Allah, peace and blessings of Allah be upon him, said: "There is no contagion, and no superstition, but the good omen pleases me." They said: "O Prophet of Allah, what is the good omen?" He said: "The good word."
