In Qur'an Allah almighty says: (O mankind! A similitude has been coined, so listen to it (carefully): Verily those on whom you call besides Allah, cannot create (even) a fly, even though they combine together for the purpose. And if the fly snatches away a thing from them, they will have no power to release it from the fly. So weak are (both) the seeker and the sought.)(Sûrat Al-Hajj-verse73), in this verse Allah wants us to understand how much this insect is important and to know that He almighty didn't create it without purpose as He says in another verse: (And has subjected to you all that is in the heavens and all that is in the earth; it is all as a favour and kindness from Him. Verily, in it are signs for a people who think deeply.)(Sûrat Al-Jâthiyah-verse 13).
Also prophet Mohamed (Peace be upon him) tells us about the benefit of the fly: ("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.")( Narrated by Abu Huraira).
Let us think rationally, who told that illiterate prophet about this scientific fact 1400 years ago?
