(20) باب رُقْيَةِ الْمَرِيضِ بِالْمُعَوِّذَاتِ وَالنَّفْثِ
'A'isha reported that when any of the members of the household fell ill Allah's Messenger (ﷺ) used to blow over him by reciting Mu'awwidhatan, and when he suffered from illness of which he died I used to blow over him and rubbed his body with his hand for his hand had greater healing power than my hand.
