عَنْ أَبِي هُرَيْرَةَ
قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْأَرْبَعِ: مِنْ عِلْمٍ لَا يَنْفَعُ وَمِنْ قَلْبٍ لَا يَخْشَعُ وَمِنْ نَفْسٍ لَا تَشْبَعُ وَمِنْ دُعَاءٍ لَا يُسْمَعُ»
knowledge which does not profit, a heart which is not submissive, an appetite which is insatiable, and a supplication which is not heard. Ahmad, Abu Dawud and Ibn Majah transmitted it. Tirmidhi transmitted it from Abdallah ibn Amr, and Nasai from both sources.
