Arabic (Original)
حَدَّثَنَا يَزِيدُ قَالَ ثَنَا ابْنُ أَبِي ذِئْبٍ عَنْ سَعِيدِ بْنِ خَالِدٍ قَالَ دَخَلْتُ عَلَى أَبِي سَلَمَةَ فَأَتَانَا بِزُبْدٍ وَكُتْلَةٍ فَأُسْقِطَ ذُبَابٌ فِي الطَّعَامِ فَجَعَلَ أَبُو سَلَمَةَ يَمْقُلُهُ بِأُصْبُعِهِ فِيهِ فَقُلْتُ يَا خَالُ مَا تَصْنَعُ فَقَالَ إِنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ حَدَّثَنِي عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ أَحَدَ جَنَاحَيْ الذُّبَابِ سُمٌّ وَالْآخَرَ شِفَاءٌ فَإِذَا وَقَعَ فِي الطَّعَامِ فَامْقُلُوهُ فَإِنَّهُ يُقَدِّمُ السُّمَّ وَيُؤَخِّرُ الشِّفَاءَ.
English Translation
Yazid narrated to us, saying: Ibn Abi Dhi'b narrated to us, from Sa'id b. Khalid, who said: I entered upon Abu Salamah, and he brought us butter and a lump of curd, and a fly fell into the food, and Abu Salamah began to dip it in with his finger. I said, "O uncle, what are you doing?" He said, "Abu Sa'id al-Khudri narrated to me from the Messenger of Allah, peace and blessings be upon him, that he said: 'One of the fly's two wings carries disease and the other carries its cure; so when it falls into food, submerge it, for it puts forward the disease and holds back the cure.'"
