It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that among the supplications of the Messenger of Allah (peace and blessings be upon him) was this: 'Allahumma inni a'udhu bika min 'ilmin la yanfa', wa qalbin la yakhsha', wa du'a'in la yusma', wa nafsin la tashba', wa minal-ju'i fa innahu bi'sad-daji', wa minal-khiyanati fa bi'satil-bitanah, wa minal-kasali wal-bukhli wal-jubn, wa minal-haram, wa min an uradda ila ardhalil-'umur, wa min fitnatid-dajjal, wa 'adhabil-qabr, wa fitnatil-mahya wal-mamat. Allahumma inna nas'aluka quluban awwahatan mukhbitatan munibatan fi sabilik. Allahumma inna nas'aluka 'aza'ima maghfiratik, wa munjiyati amrik, was-salamata min kulli ithm, wal-ghanimata min kulli birr, wal-fawza bil-jannah, wan-najata minan-nar' (O Allah, I seek refuge in You from knowledge that does not benefit, from a heart that does not humble itself (in fear of You), from a supplication that is not heard (not accepted), and from a soul that is never satisfied; and I seek refuge from hunger, for it is the worst bedfellow; and from treachery, for it is the worst inner trait; and I seek refuge from laziness, miserliness, cowardice, extreme old age, and from being returned to the most feeble age; and also from the trial of the Dajjal, the punishment of the grave, and the trials of life and death. O Allah, we ask You for hearts that sigh and cry out in Your path, that are humble and that turn to You in repentance. O Allah, we ask You for the means that make Your forgiveness certain, the aspects of Your command that bring salvation, safety from every sin, an abundant share of every good deed, success in attaining Paradise, and deliverance from the Fire). And when he (peace and blessings be upon him) prostrated, he would say: 'Allahumma sajada laka sawadi wa khayali, wa bika amana fu'adi, abu'u bi ni'matika 'alayya, wa hadha ma janaytu 'ala nafsi, ya 'Azim, ya 'Azim, ighfir li, fa innahu la yaghfirudh-dhunubal-'azimata illar-Rabbul-'Azim' (O Allah, my being and my spirit have prostrated before You, and my heart has believed in You. I acknowledge Your blessings upon me, and these are the sins I have committed against myself. O Most Great Lord, O Most Great Lord, forgive me, for none can forgive great sins except the Most Great Lord). This hadith is sahih al-isnad (authentic in its chain); however, the two Shaykhs did not narrate from Humayd al-A'raj al-Kufi; rather, they agreed on recording the narration of Humayd bin Qays al-A'raj al-Makki. As for the opening part of the hadith (seeking refuge from four things), narrations of it have also been reported from Sayyiduna Abu Hurayrah and Sayyiduna Abdullah bin Amr.
