مسند أحمد

It was narrated that `Ali bin Abi Talib (رضي الله عنه) said: I fell sick and the Messenger of Allah (ﷺ) passed by me when I was saying O Allah, if my time has come then grant me relief; if it has not yet come then raise me in status; and if this is a trial then grant me patience. The Messenger of Allah (ﷺ) said: “What did you say?” He repeated to him what he had said, and he nudged him with his foot and said: `O Allah, grant him well being` or “O Allah, heal him.” - Shu`bah was not certain. He [‘Ali] said: And I never suffered that sickness again after that.
