Zayd ibn Arqam reported: The Messenger of Allah, peace and blessings be upon him, said:
اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عِلْمٍ لاَ يَنْفَعُ وَمِنْ قَلْبٍ لاَ يَخْشَعُ وَمِنْ نَفْسٍ لاَ تَشْبَعُ وَمِنْ دَعْوَةٍ لاَ يُسْتَجَابُ لَهَا
O Allah, I seek refuge in you from knowledge that does not benefit, from a heart that is not reverent, from a soul that is not content, and from a supplication that is not answered.
