Musnad Ahmad 32:239

Waki’ narrated to us, from Shu’bah and al-Dastawa’i, from Qatadah, from Anas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no *tiyarah* (superstitious omen), and the *fa’l* (good omen) pleases me." He said: "And the *fa’l* is the good, pleasant word."
