It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) used to supplicate: 'Allahumma inni a'udhu bika min al-arba': min 'ilmin la yanfa', wa qalbin la yakhsha', wa nafsin la tashba', wa du'a'in la yusma'' (O Allah, I seek refuge in You from four things: from knowledge that does not benefit, from a heart that is not humble, from a soul that is never satisfied, and from a supplication that is not heard). It has an authentic supporting narration (shahid) from the narration of Sayyiduna Anas bin Malik (may Allah be pleased with him) on the condition of Imam Muslim.
