Chapter: Reciting Al-Mu'awwidhat As Ruqyah For The Sick, And Blowing Over Them
(20)
باب رُقْيَةِ الْمَرِيضِ بِالْمُعَوِّذَاتِ وَالنَّفْثِ ‏‏
Sahih Muslim 2192 a

'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.

حَدَّثَنِي سُرَيْجُ بْنُ يُونُسَ، وَيَحْيَى بْنُ أَيُّوبَ، قَالاَ حَدَّثَنَا عَبَّادُ بْنُ عَبَّادٍ، عَنْ هِشَامِ، بْنِ عُرْوَةَ عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا مَرِضَ أَحَدٌ مِنْ أَهْلِهِ نَفَثَ عَلَيْهِ بِالْمُعَوِّذَاتِ فَلَمَّا مَرِضَ مَرَضَهُ الَّذِي مَاتَ فِيهِ جَعَلْتُ أَنْفُثُ عَلَيْهِ وَأَمْسَحُهُ بِيَدِ نَفْسِهِ لأَنَّهَا كَانَتْ أَعْظَمَ بَرَكَةً مِنْ يَدِي ‏.‏ وَفِي رِوَايَةِ يَحْيَى بْنِ أَيُّوبَ بِمُعَوِّذَاتٍ ‏.‏
