Jami` at-Tirmidhi Book 48, Hadith 197
that the Prophet (ﷺ) used to say in his Witr: “O Allah, I seek refuge in your pardon from Your Punishment, and I seek refuge in You from You, I am not capable of extolling You as You have extolled Yourself (Allāhumma innī a`ūdhu bi-riḍāka min sakhaṭika, wa a`ūdhu bi-mu`āfātika min `uqūbatika, wa a`ūdhu bika minka, lā uḥsī thanā’an `alaika, anta kamā athnaita `alā nafsik).”
“Whenever the Prophet (ﷺ) would visit an ill person, he would said:‘ adh-hibil-ba’sa rabban-nās, washfi antash-shāfi, lā shifā’a illā shifā’uka shifā’an lā yughādiru saqama).’”
“Sa`d used to teach his children these words just as the Muktib teaches children, he would say: ‘Indeed, the Messenger of Allah (ﷺ) used to seek refuge by saying them at the end of (every) Salat: O Allah I seek refuge in You from cowardliness, I seek refuge in You from miserliness, I seek refuge in You from feeble old age, and I seek refuge in You from the trial of the world, and the punishment of the grave (Allāhumma innī a`ūdhu bika minal-jubn, wa a`ūdhu bika minal-bukhl, wa a`ūdhu bika min ardhalil-`umur, wa a`ūdhu bika min fitnatid-dunyā wa `adhābil qabr).’”
