أَخْبَرَنَا سُلَيْمَانُ بْنُ حَرْبٍ، نا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثُمَامَةَ بْنِ عَبْدِ اللَّهِ بْنِ أَنَسٍ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: ((إِذَا وَقَعَ الذُّبَابُ فِي إِنَاءِ أَحَدِكُمْ فَلْيَغْمِسْهُ فَإِنَّ فِي أَحَدِ جَنَاحَيْهِ دَاءً وَفِي الْآخَرِ دَوَاءً)) .
Narrated Abu Huraira (may Allah be pleased with him) from the Messenger of Allah (peace and blessings be upon him), he said: "When a fly falls into the vessel of any one of you, he should immerse it, for indeed in one of its wings is disease and in the other is cure (healing)."
