Sahih al-Bukhari, 5016

Rapporté par `Aisha : Chaque fois que le Messager d’Allah (ﷺ) tombait malade, il récitait les Mu’awwidhat (Sourate Al-Falaq et Sourate An-Nas), puis soufflait sur son corps. Quand sa maladie est devenue grave, je récitais ces deux sourates et je passais ses mains sur son corps, espérant la bénédiction de ces versets

Narrated `Aisha:Whenever Allah's Messenger (ﷺ) became sick, he would recite Mu'awwidhat (Surat Al-Falaq and Surat An- Nas) and then blow his breath over his body. When he became seriously ill, I used to recite (these two Suras) and rub his hands over his body hoping for its blessings
