Chapter 35: Supplication
Abu Hurairah told that the Messenger of Allah (saas) said: 'Allahumma! Inni a' udhu bika minal-arba': 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 four things: From knowledge that is of no benefit, from a heart that does not fear (You), from a soul that is never satisfied, and from a supplication that is not heard].'"
Sunan Ibn Majah 3837
