Jami` at-Tirmidhi Book 48, Hadith 196
“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).’”
“I was ill and the Messenger of Allah (ﷺ) passed by me while I was saying: ‘O Allah, if my term has come, then give me relief, and if it is coming later, then make my life more bountiful, and if it is a trial then make me patient (Allāhumma, in kāna ajalī qad ḥaḍara fa ariḥnī, wa in kāna muta’akh-khiran fa arfighnī, wa in kāna balā’an fa ṣabbirnī).’ So the Messenger of Allah (ﷺ) said: ‘What did you say?’” He said: “So he repeated to him what he said.” He (one of the narrators) said: So he struck him with his foot and said: “O Allah, grant him health (Allāhumma `āfihi)” – or – “heal him (ishfihi).” – Shu`ba is the one who doubted. He said: “So I did not suffer from my ailment again.”
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).”
