Sahih al-Bukhari 5735

Narrated `Aisha:

During the Prophet's fatal illness, he used to recite the Mu'auwidhat (Surat An-Nas and Surat Al- Falaq) and then blow his breath over his body. When his illness was aggravated, I used to recite those two Suras and blow my breath over him and make him rub his body with his own hand for its blessings." (Ma`mar asked Az-Zuhri: How did the Prophet (ﷺ) use to blow? Az-Zuhri said: He used to blow on his hands and then passed them over his face.)

حَدَّثَنِي إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَنْفُثُ عَلَى نَفْسِهِ فِي الْمَرَضِ الَّذِي مَاتَ فِيهِ بِالْمُعَوِّذَاتِ، فَلَمَّا ثَقُلَ كُنْتُ أَنْفِثُ عَلَيْهِ بِهِنَّ، وَأَمْسَحُ بِيَدِ نَفْسِهِ لِبَرَكَتِهَا‏.‏ فَسَأَلْتُ الزُّهْرِيَّ كَيْفَ يَنْفِثُ قَالَ كَانَ يَنْفِثُ عَلَى يَدَيْهِ، ثُمَّ يَمْسَحُ بِهِمَا وَجْهَهُ‏.‏
