HADITH OF THE DAY
WHEN A FLY FALLS IN A VESSEL
Narrated by Abu Huraira
Allah's Messenger (Peace & Blessings of Allah upon Him) 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."
[Vol-7 Hadith-673 Sahih Al-Bukhari]
