Musnad Ahmad 30:1658

Al-Khuza'i narrated to us, he said: Layth narrated to us, from Sa'id, from his brother 'Abbad, that he heard Abu Hurayrah saying: The Messenger of Allah, may Allah bless him and grant him peace, used to say: "O Allah, I seek refuge in You from four: from knowledge that does not benefit, and from a heart that does not humble itself, and from a soul that is not satisfied, and from a supplication that is not heard."
