Musnad Abu Ya'la al-Mawsili 115:4

Abu Nasr al-Tammar narrated to us, Hammad narrated to us, from Qatadah, from Anas bin Malik, that the Prophet (peace be upon him) used to say: "O Allah, I seek refuge in You from knowledge that does not benefit, and from a deed that is not raised (accepted), and from a heart that does not humble itself, and from a statement that is not heard."
