عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ إِذَا اشْتَكَى وَفِي رِوَايَةٍ كَانَ فِي مَرَضِهِ الَّذِي قُبِضَ فِيهِ يَقْرَأُ عَلَى نَفْسِهِ بِالْمُعَوِّذَاتِ وَيَنْفُثُ قَالَتْ عَائِشَةُ فَلَمَّا اشْتَدَّ وَجَعُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كُنْتُ أَنَا أَقْرَأُ عَلَيْهِ وَأَمْسَحُ عَنْهُ بِيَدِهِ رَجَاءَ بَرَكَتِهَا
It is narrated from Sayyida Aisha (may Allah be pleased with her) that when the Messenger of Allah (peace and blessings be upon him) fell ill with his final illness, he would recite the Mu'awwidhat and blow over himself. Sayyida Aisha says: When the illness of the Prophet (peace and blessings be upon him) became severe, I would recite these Surahs and, due to the blessing of his hand, I would pass his hand over his body.
