Jami' at-Tirmidhi 3564

Ali said:“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.”
