وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا اشْتَكَى نَفَثَ عَلَى نَفْسِهِ بِالْمُعَوِّذَاتِ وَمَسَحَ عَنْهُ بِيَدِهِ فَلَمَّا اشْتَكَى وَجَعَهُ الَّذِي تُوُفِّيَ فِيهِ كُنْتُ أَنْفِثُ عَلَيْهِ بِالْمُعَوِّذَاتِ الَّتِي كَانَ يَنْفِثُ وَأَمْسَحُ بِيَدِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَفِي رِوَايَةٍ لِمُسْلِمٍ قَالَتْ: كَانَ إِذَا مَرِضَ أَحَدٌ مِنْ أَهْلِ بَيْتِهِ نَفَثَ عَلَيْهِ بِالْمُعَوِّذَاتِ
English Translation
She said that when the Prophet had a complaint he would blow on himself, ejecting saliva, reciting the Mu'awwidhat (See n. 1, p, 197.), and wipe himself with his hand. She said, “When he suffered from the pain of which he died, I would blow on him ejecting saliva and recite the Mu'awwidhat as he did, and would take the Prophet’s hand to wipe him.” (Bukhari and Muslim.) In a version by Muslim she said, “When one of his family was ill he would blow on him ejecting saliva and recite the Mu'awwidhat.
