Arabic (Original)
حَدَّثَنَا وَكِيعٌ عَنْ إِبْرَاهِيمَ بْنِ الْفَضْلِ عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا وَقَعَ الذُّبَابُ فِي طَعَامِ أَحَدِكُمْ أَوْ شَرَابِهِ فَلْيَغْمِسْهُ إِذَا أَخْرَجَهُ فَإِنَّ فِي أَحَدِ جَنَاحَيْهِ دَاءً وَفِي الْآخَرِ شِفَاءً وَإِنَّهُ يُقَدِّمُ الدَّاءَ.
English Translation
Waki' told us, from Ibrahim ibn al-Fadl, from Sa'id ibn Abi Sa'id, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "When a fly falls into the food or drink of one of you, let him dip it in fully when he takes it out, for in one of its wings is disease and in the other is a cure, and it puts forward the disease first."
