Abu Hurayrah narrated, The Prophet said :
"If a housefly falls into the drink of anyone of you,
he should immerse it completely in the liquid, then remove it, for one of its
wings has the disease and the other has the cure."
Explanation from hadith :
This Hadith means that the fly carries on one of its wings a
disease, and on the other a cure from the same disease. When a fly falls into a
container (of food or drink), it puts forward the wing carrying the microbe, as
a self-defense. Imam Ibn Hajar said in his commentary on the hadith that one of
the scholars observed that the fly protects itself with its left wing, so it
can be deduced that it carries the cure or the antidote on the right wing. So
if the fly is immersed in whatever it falls on, the antidote will destroy the
venom or the microbe with the will of Allah.
Some people are not pleased with the idea of immersing a fly in one's
food or drink. However, this can be only applied in cases of emergency. When,
for example, someone is in a desert, having only little water or drink. Such a
person has no choice but to do as the Prophet recommended. Otherwise, he will
die from thirst or infection. If someone disdains eating that food or drink, he
does not have to do so, but he does not have the right to disclaim the
authenticity of the hadith. The hadith is strongly authentic, as it is narrated
by Imam al-Bukhari.
Flies are very common on earth. They are almost 87000
species. It has been scientifically proved that they feed on garbage and waste
organic matter of the vast numbers of bacteria, viruses and other various
microbes and germs.
Bacteria are very small living organisms. They live in
billions in one gram of agricultural land and in millions in one drop of
saliva. The effect of bacteria on the biological life on earth is unlimited,
without it no crops could grow, and without crops there would be no life for man
and animals on earth. Most of the bacteria are harmless, but some cause several
diseases.
Viruses are, in fact, nucleic acids (either DNA or RNA).
Allah the Almighty gave them the ability to enclose themselves by a protein
coat, to form separate units called the "virion". The virus particle
or the "virion" has the ability to invade living cells (host cell),
inciting them to produce more viruses or destroying the tissues of this host
cell. That is why viruses are responsible for many diseases, which affect
plants, animals and man.There is a type of virus, which infects, bacteria cells,
known as "Bacteriophage." The killing type of these viruses is known
as "Virulent Bacteriophage", while the non-killing type is known as
"Temperate Bacteriophage". It is of the Divine Ability of Allah,
Glorified be He, to create everything in this universe in pairs, so that, it is
only Allah, Who is the One, Who has no partner. Thus, Allah created male and
female, day and night, positive and negative, as He created the bacteria and
the "Bacteriophage." It is only Allah, Who is the One, Who has no
partner.
Allah, the Almighty, gave the fly the ability to carry the
germ on one wing and its antidote on the other. Otherwise the fly species would
have perished by now, exposed to all these germs. However, they still exist in
more than 87000 species.
The fly carries the viruses of many diseases, which are
consequently transferred to man's food, drink and body. Of these viral diseases
are common flu, measles, mumps, chickenpox, warts, yellow fever, infectious
liver diseases, some cases of paralysis, some types of cancer, and some chronic
diseases of the central nervous system including multiple sclerosis.
Viruses also cause many diseases, which effect cattle, sheep
and birds. Some of these diseases are encephalitis, aphthous fever (foot and
mouth diseases) and duck plague, which could be transferred to man through the
infected animal. Some crops such as potatoes, tomatoes, bananas and sugarcane
can also be destroyed by viral infections.
"The virulent Bacteriophage" kills the bacterial
cell that it invades in a very short time. While the "Temperate
Bacteriophage" keeps the bacterial cell that it invades alive. It acquires
a kind of immunity against the same virus or produce similar viruses. This
explains why the fly carries pathogen on one wing and its antidote on the
other.
A group of Muslim researchers in Egypt and Saudi Arabia
carried several experiments on containers of water, honey and different juices.
They exposed them to the flies. Then they immersed some flies in some of these
containers. The microscopic examination showed that the liquids in which no
flies were immersed were full of bacteria and viruses, while the others where
the flies were totally immersed had none.
It was discovered that there are antidotes for pathogens,
and that there are various types of bacteria and "Bacteriophages",
only in the last decades of the 20th century.
The Prophet (PBUH) alluded to these 1400 years ago, when
humans knew almost nothing of the facts of modern science. But given this type
of information with such accuracy, that one wing carries the antidote to the
pathogen carried by the other, could only be of the Divine Revelation taught to
the Prophet (PBUH) by Allah the Almighty
