Ayesha reported that whenever the Prophet ﷺ fell ill, he would recite the two surahs of refuge over himself and blow lightly. She said, "When his illness grew severe, I began reciting them over him and blowing, and wiping him with his own right hand, seeking its blessing."
حدثنا حماد بن خالد قال حدثنا مالك عن الزهري عن عروة
أن النبي ﷺ كان إذا مرض قرأ على نفسه بالمعوذتين وينفث قالت عائشة فلما ثقل جعلت أنفث عليه بهما وأمسح بيمينه التماس بركتها
