Chapter 76: Medicine
Narrated 'Aisha: The Prophet, during his fatal ailment used to blow (on his hands and pass them) over his body while
reciting the Mu' auwidhat (Surat-an-Nas and Surat-al-Falaq). When his disease got aggravated, I used
to recite them for him and blow (on his hands) and let him pass his hands over his body because of its
blessing. (Ma 'mar asked Ibn Shihab: How did he use to do Nafth? He said: He used to blow on his
hands and then pass them over his face.)
