صحيح البخاري 5016

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

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
