حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، عَنْ عُتْبَةَ بْنِ مُسْلِمٍ، مَوْلَى بَنِي تَيْمٍ عَنْ عُبَيْدِ بْنِ حُنَيْنٍ، مَوْلَى بَنِي زُرَيْقٍ عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِذَا وَقَعَ الذُّبَابُ فِي إِنَاءِ أَحَدِكُمْ، فَلْيَغْمِسْهُ كُلَّهُ، ثُمَّ لْيَطْرَحْهُ، فَإِنَّ فِي أَحَدِ جَنَاحَيْهِ شِفَاءً وَفِي الآخَرِ دَاءً ".
