وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا اشْتَكَى يَقْرَأُ عَلَى نَفْسِهِ بِالْمُعَوِّذَاتِ وَيَنْفِثُ ‏.‏ قَالَتْ فَلَمَّا اشْتَدَّ وَجَعُهُ كُنْتُ أَنَا أَقْرَأُ عَلَيْهِ وَأَمْسَحُ عَلَيْهِ بِيَمِينِهِ رَجَاءَ بَرَكَتِهَا ‏.‏
