"The Messenger of Allah [SAW] used to say: 'Allahumma inni a'udhu bika min al-arba': min 'ilmin la yanfa'u, wa min qalbin la yakhsha'u, wa min nafsin la tashba'u, wa min du'a'in la yusma'u (O Allah, I seek refuge in You from four: From knowledge that is of no benefit, from a heart that is not humble, from a soul that is not satisfied and from a supplication that is not answered.)'"  

أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ يَقُولُ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الأَرْبَعِ مِنْ عِلْمٍ لاَ يَنْفَعُ وَمِنْ قَلْبٍ لاَ يَخْشَعُ وَمِنْ نَفْسٍ لاَ تَشْبَعُ وَمِنْ دُعَاءٍ لاَ يُسْمَعُ
