Musnad Ahmad 32:1730

Hassan ibn Musa narrated to us, Hammad ibn Salamah narrated to us, from Qatadah, from Anas ibn Malik, that the Messenger of Allah, may Allah bless him and grant him peace, 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 (accepted)."
