[Machine] The Prophet ﷺ said, "If a fly falls into the vessel of one of you, then dip it in and take it out, for indeed in one of its wings there is a disease, and in the other, there is a cure." Hammād and Habīb bin al-Shahīd narrated from Muhammad bin Sīrīn, from Abu Huraira, from the Prophet ﷺ with a similar wording.
أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا وَقَعَ الذُّبَابُ فِي إِنَاءِ أَحَدِكُمْ فَلْيَغْمِسْهُ فَإِنَّ فِي أَحَدِ جَنَاحَيْهِ دَاءً وَفِي الْآخَرِ دَوَاءً قَالَ حَمَّادٌ وَحَبِيبُ بْنُ الشَّهِيدِ عَنْ مُحَمَّدِ بْنِ سِيرِينَ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ مِثْلَهُ
