It was narrated from 'Abdullah bin Amr that:

The Prophet (ﷺ) [ﷺ] used to seek refuge (with Allah) from four things: From knowledge that is of no benefit, from a heart that does not feel humble, from a supplication that is not heard, and a soul that is never satisfied.

أَخْبَرَنَا يَزِيدُ بْنُ سِنَانٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنْ أَبِي سِنَانٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي الْهُذَيْلِ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَتَعَوَّذُ مِنْ أَرْبَعٍ مِنْ عِلْمٍ لاَ يَنْفَعُ وَمِنْ قَلْبٍ لاَ يَخْشَعُ وَدُعَاءٍ لاَ يُسْمَعُ وَنَفْسٍ لاَ تَشْبَعُ ‏.‏
