حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو خَالِدٍ الأَحْمَرُ، عَنِ ابْنِ عَجْلاَنَ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كَانَ مِنْ دُعَاءِ النَّبِيِّ ـ صلى الله عليه وسلم ـ " اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عِلْمٍ لاَ يَنْفَعُ وَمِنْ دُعَاءٍ لاَ يُسْمَعُ وَمَنْ قَلْبٍ لاَ يَخْشَعُ وَمِنْ نَفْسٍ لاَ تَشْبَعُ " .
It was narrated that Abu Hurairah said:"One of the supplications that the Prophet used to say was: 'Allahumma, inni a'udhu bika min 'ilmin la yanfa'u, wa mindu'a'in la yusma'u, wa min qalbin la yakhsha'u, wa min nafsin la tashba'u [O Allah, I seek refuge with You from knowledge that is of no benefit, from a supplication that is not heard, from a heart that does not fear (You) and from a soul that is not satisfied
