'A'isha reported that when Messenger of Allah ﷺ fell ill, he recited over his body Mu'awwidhatan and blew over him and when his sickness was aggravated I used to recite over him and rub him with his band with the hope that it was more blessed.  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا اشْتَكَى يَقْرَأُ عَلَى نَفْسِهِ بِالْمُعَوِّذَاتِ وَيَنْفُثُ فَلَمَّا اشْتَدَّ وَجَعُهُ كُنْتُ أَقْرَأُ عَلَيْهِ وَأَمْسَحُ عَنْهُ بِيَدِهِ رَجَاءَ بَرَكَتِهَا  

[Machine] About the Prophet (PBUH), whenever he fell sick, he used to recite the "Mu'awwidhat" (i.e. Surah Al-Falaq and Surah An-Nas) and blow onto himself.  

عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ إِذَا مَرِضَ يَقْرَأُ عَلَى نَفْسِهِ بِالْمُعَوِّذَاتِ وَيَنْفُثُ  

the wife of Prophet ﷺ said: When the Messenger of Allah ﷺ suffered from some pain, he recited mu'awwadhat in his heart and blew (them over him). When the pain became severe, I recited (them) over him and wiped him with his hand in the hope of its blessing. (Using translation from Abū Dāʾūd 3902)  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا اشْتَكَى يَقْرَأُ عَلَى نَفْسِهِ بِالْمُعَوِّذَاتِ وَيَنْفُثُ فَلَمَّا اشْتَدَّ وَجَعُهُ كُنْتُ أَقْرَأُ عَلَيْهِ وَأَمْسَحُ عَنْهُ بِيَدِهِ رَجَاءَ بَرَكَتِهَا  

“Whenever the Prophet ﷺ fell ill, he would recite the Mu’awwidhat and blow, and when his pain grew worse, I would recite over him and wipe his hand over him, hoping for its blessing.” (Using translation from Ibn Mājah 3529)  

أَنَّ النَّبِيَّ ﷺ «كَانَ إِذَا اشْتَكَى قَرَأَ عَلَى نَفْسِهِ بِالْمُعَوِّذَاتِ وَيَنْفُثُ فَلَمَّا اشْتَدَّ وَجَعُهُ كُنْتُ أَقْرَأُ عَلَيْهِ وَأَمْسَحُ عَنْهُ بِيَدِهِ رَجَاءَ بَرَكَتِهَا»  

[Machine] The Messenger of Allah ﷺ used to recite the Mu'awwathat (Surahs of refuge: Surah Al-Falaq and Surah An-Nas) on himself when he felt unwell and blew upon himself.  

«كَانَ رَسُولُ اللهِ ﷺ إِذَا اشْتَكَى قَرَأَ عَلَى نَفْسِهِ بِالْمُعَوِّذَاتِ وَيَنْفُثُ»
