Musnad Ahmad 30:2701

Hajjaj narrated to us, he said: Layth narrated to us, he said: Sa'id ibn Abi Sa'id narrated to me, from his brother 'Abbad ibn Abi Sa'id, 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."
