(20) باب رُقْيَةِ الْمَرِيضِ بِالْمُعَوِّذَاتِ وَالنَّفْثِ
'A'isha reported that when Allah's Messenger (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.
