Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) used to say: (that is, the Noble Prophet (peace and blessings be upon him) used to recite this supplication) "O Allah! I seek refuge in You from a soul that is never satisfied, and I seek refuge in You from a prayer that is of no benefit, and I seek refuge in You from a supplication that is not heard, and I seek refuge in You from a heart that has no humility."
