Sahih al-Bukhari Book 75, Hadith 35
Whenever Allah's Messenger (ﷺ) paid a visit to a patient, or a patient was brought to him, he used to invoke
Allah, saying, "Take away the disease, O the Lord of the people! Cure him as You are the One Who
cures. There is no cure but Yours, a cure that leaves no disease."
I heard the Prophet (ﷺ) , who was resting against me, saying, "O Allah! Excuse me and bestow Your Mercy on me and let me join with the highest companions (in Paradise)." See Qur'an (4.69)
The Prophet (ﷺ) came to me while I was ill. He performed ablution and threw the remaining water on me (or said, "Pour it on him) " When I came to my senses I said, "O Allah's Messenger (ﷺ)! I have no son or father to be my heir, so how will be my inheritance?" Then the Verse of inheritance was revealed.
