Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)

Bukhari :: Book 5 :: Volume 59 :: Hadith 714

Narrated 'Aisha:

Whenever Allah's Apostle became ill, he used to recite Al-Muawidhatan (i.e. the last two Suras of the Qur'an) and then blow his breath and passed his hand over himself. When he had his fatal illness, I started reciting Al-Muawidhatan and blowing my breath over him as he used to do, and then I rubbed the hand of the Prophet over his body.
