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
