Sahih Muslim | Book 26 | Hadith Number 5432

Narrated by 'Aisha
'Aisha reported: When any person amongst us fell ill, Allah's Messenger (may peace he upon him) used to rub him with his right band and then say: O Lord of the people, grant him health, heal him, for Thou art a Greet Healer. There is no healer, but with Thy healing Power one is healed and illness is removed. She further added: When Allah's Messenger (may peace be upon him) fell ill, and his illness took a serious turn I took hold of his hand to that I should do with it what he ward to do with that (i.e. I would rub his body with his sacred hand). But he withdrew his hand from my hand and then said: O Allah, pardon me and make me join the companionship on She said. I was gazing at him constantly whereas he had passed away.
