Musnad Ahmad 1153:173

Abu Mu’awiyah narrated to us, he said: Al-A’mash narrated to us, from Muslim, from Masruq, from ‘Aishah, she said: The Messenger of Allah, peace and blessings of Allah be upon him—and Ibn Ja’far said: Shu’bah narrated to us, from Sulayman, from Abu al-Duha, from Masruq, from ‘Aishah, she said: The Messenger of Allah, peace and blessings of Allah be upon him, used to seek refuge with these words: "Remove the harm, O Lord of the people, and heal, for You are the Healer. There is no healing but Your healing, a healing that leaves behind no illness." She said: When the Messenger of Allah, peace and blessings of Allah be upon him, became heavy in his illness in which he died, I took his hand and began to wipe him with it and say them. She said: He withdrew his hand from me, then said: "O Lord, forgive me and join me with the Highest Companion." Abu Mu’awiyah said: She said: This was the last of what I heard of his speech. Ibn Ja’far said: Indeed, the Prophet, peace and blessings of Allah be upon him, used to, when he visited a sick person, wipe him with his hand and say: "Remove the harm."
