(64) باب الاِسْتِعَاذَةِ مِنْ دُعَاءٍ لاَ يُسْمَعُ
Abu Hurairah said:
"The Messenger of Allah [SAW] used to say: 'Allahumma inni a'udhu bika min 'ilmin la yanfa'u, wa min qalbin la yakhsha'u, wa min nafsin la tashba'u, wa min du'a'in la yusma' (O Allah, I seek refuge with You from knowledge that is of no benefit, a heart that is not humble, a soul that is not satisfied and a supplication that is not heard.)'"
