Whenever Allâh's Messenger (ﷺ) became ill, he used to recite the Mu'awwidhât (Sûrah No. 113, 114) 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 Mu'awwidhât and blowing my breath over him as he used to blow and made the hand of the Prophet (ﷺ) pass over his body. [5:723-O.B]
