When fly falls into water

Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, "If a fly falls in the vessel of any of you, let him dip all of it (into the vessel) and then throw it away, for in one of its wings there is a disease and in the other there is healing (antidote for it) i e. the treatment for that disease."

[Sahih al-Bukhari Hadith No. 5782]

قال ابن القيم : " فَهُوَ دَلِيلٌ ظَاهِرُ الدّلَالَةِ جِدّا عَلَى أَنّ الذّبَابَ إذَا مَاتَ فِي مَاءٍ أَوْ مَائِعٍ فَإِنّهُ لَا يُنَجّسُهُ ، وَهَذَا قَوْلُ جُمْهُورِ الْعُلَمَاءِ ، وَلَا يُعْرَفُ فِي السّلَفِ مُخَالِفٌ فِي ذَلِكَ

Ibn Al-Qayyim said: This is very clear evidence that the fly, when it dies in water or [any] liquid, it does not make it impure. And this is the opinion of the majority of scholars and no opposition, among the Salaf, is known to this.
