Sahih al-Bukhari, 4439

Rapporté par `Aisha : Chaque fois que le Messager d’Allah (ﷺ) tombait malade, il récitait les deux dernières sourates du Coran (Al-Mu’awwidhatayn), soufflait dessus, puis passait ses mains sur son corps. Lorsqu’il fut atteint de sa maladie mortelle, je me mis à réciter ces deux sourates et à souffler sur lui comme il le faisait, puis je passai la main du Prophète (ﷺ) sur son corps

Narrated Aisha:Whenever Allah's Messenger (ﷺ) became ill, he used to recite the Muawidhatan (i.e. the last two surahs of the Qur'an) and blow his breath over himself (after their recitation ) and rubbed his hands over his body. So when he was afflicted with his fatal illness. I started reciting the Muawidhatan and blowing my breath over him as he used to do and then I rubbed the hand of the Prophet (ﷺ) over his body
