'A'isha reported that when any of the members of the household fell ill Messenger of Allah 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.
كَانَ رَسُولُ اللَّهِ ﷺ 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
