Zaid Bin Arqam [radiyallaahu-anhu] narrated that the Prophet [sallal-laahu-alayhi-wasallam] used to say:

اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عِلْمٍ لَا يَنْفَعُ وَمِنْ قَلْبٍ لَا يَخْشَعُ وَمِنْ نَفْسٍ ‏لَا تَشْبَعُ ‏ ‏وَمِنْ دَعْوَةٍ لَا يُسْتَجَابُ لَهَا

O Allaah! I seek refuge with You from knowledge that does not benefit; from a heart that does not fear [You]; from a soul that does not get satisfied and from a supplication that is not answered.


[Reported by Muslim 2722]
