On the authority of the Prophet ﷺ, he said: "When a fly falls into the vessel of any one of you, let him immerse it, for indeed in one of its wings there is a disease and in the other there is a cure." Abu Muhammad said, "Except for Hammaad, Thumamah, and Anas in the place of Abu Hurayrah, and a group that says it is from al-Qaqa' (another narrator) from Abu Hurayrah." And the narration of Ubayd ibn Hunayn is the most authentic. – Weak Chain

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا وَقَعَ الذُّبَابٌ فِي إِنَاءِ أَحَدِكُمْ فَلْيَغْمِسْهُ فَإِنَّ فِي أَحَدِ جَنَاحَيْهِ دَاءً وَفِي الْآخَرِ شِفَاءً قَالَ أَبُو مُحَمَّد قَالَ غَيْرُ حَمَّادٍ ثُمَامَةُ عَنْ أَنَسٍ مَكَانَ أَبِي هُرَيْرَةَ وَقَوْمٌ يَقُولُونَ عَنْ الْقَعْقَاعِ عَنْ أَبِي هُرَيْرَةَ «وَحَدِيثُ عُبَيْدِ بْنِ حُنَيْنٍ أَصَحُّ» – إسناده ضعيف
