Musnad Abu Ya'la al-Mawsili 115:29

Hadaba narrated to us, Hammam narrated to us, Qatada narrated to us, from Anas, that the Prophet (peace and blessings of Allah be upon him) said: "There is no contagion and no superstition (tiyara), but the good omen (al-fa'l) pleases me." The good word, the beautiful word.
