(2) باب الاِسْتِعَاذَةِ مِنْ قَلْبٍ لاَ يَخْشَعُ
It was narrated from 'Abdullah bin Amr that:
The Prophet [SAW] 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. (RU)
