The Messenger of Allah (ﷺ) used to say: “O Allah, I seek refuge in You from a heart that does not humble itself, and from a supplication that is not heard, and from a soul that is never satisfied, and from knowledge that does not benefit, I seek refuge in You from these four (Allāhumma innī a`ūdhu bika min qalbin lā yakhsha`u, wa min du`ā’in lā yusma`u, wa min nafsin lā tashba`u, wa min `ilmin lā yanfa`u, a`ūdhu bika min hā’ula’il-arba`).”
