Mus' ab bin Sa' d said that: Sa' d used to teach him these words, narrating from the Prophet [SAW]: "Allahumma inni a' udhu bika minal-bukhli, wa a' udhu bika minal-jubni, wa a' udhu bika an uradda ila ardhalil-' umuri, wa a' udhu bika min fitnatid-dunya wa 'adhabil-qabr (O Allah, I seek refuge with You from miserliness, and I seek refuge with You from cowardice, and I seek refuge with You from reaching the age of senility, and I seek refuge in You from the trials of this world and the torment of the grave.)"
