I just rolled upon a very surprising write up shared on a Whatsapp group, about April fool being celebrated to mock Muslims around the world, since i didn't have data, i asked the poster to Google the information he just posted to ascertain whether there's any truth about the post or just a malicious lie to put people into religious hatred/conflicts, as is people's habit of sharing unconfirmed stories.
He got all defensive, alas, here is my research concerning the rumored mockery of Muslims by Christian using April fools day.


Muslims fooled by April Fool's Day Internet

Recently a Young Sister's Group passed on a questionable
story to my daughter in which the claim was made that
Fool's Day had to do with the unthrowing of the Muslims
of Spain. Being that my husband and I are history buffs
& I have studied the history behind holidays we knew
this "claim" to be false.
It is sad that it is "dangerous" for our young Muslims to
even enter in to "religious" discussion on supposedly serious
Muslim chat groups (even gender-segregated) due to the
rampid gossip that is spread under the cloak of "truth".
This story is a clear example of how willing many Muslims
are willing to make a "boogy man" out of others, rather
than face the fact that the Loss of Spain was due to
the corruption of the MUSLIMS who fought amongst
themselves, as is often the case today in the Ummah.
Instead the Muslim Ummah wants to blame someone else
and so they accept who ever the finger is being pointed
at. What ever happened to Islamic justice? Solely because
someone is a non-Muslim does not mean they are in the
wrong and evil, while being Muslim makes one right. Nor
does being born into a Muslim family make one right and
the others wrong.
Yet this is happening. I have heard in our Ummah
statements by professors that "they aren't REAL Muslims"
in reference to Muslim American converts. I have heard
Arabs speak derogatorily about other races within the
ummah, blaming the non-Arabs for bring fitnah and
innovation into the Ummah. All of these acts are dividing
and destroying our ummah. The shatan doesn't need the
non-Muslim to send spies into the Ummah to destory us,
we have many within our own Muslim Ummah who are
more than willing to help the shatan for the sake of
Nationalism, Tribalism, Racism and Economic rankings to do
that.
We fight for the sake of buildings, but sit back and let
our Brotherhood and Sisterhood destroyed! May Allah
forgive All of Us for our inaction and our weak deens!
Below I have added the article that corrects the
misinformation that is being passed by the Muslim masses
on the email. Insha Allah, in the future we will start to
check into these claims before they are shared with our
fellow Muslims.

It Appears That Muslims Are the Fools
Now as regards the incorrect story circulating amongst
the Muslims on the Internet saying that April Fool's Day
is the celebration of the kufar over the conquest of
Muslim Spain. I felt that it was necessary to clarify a
few points in the interest of truth, inshallah.
Bismillah Al Hamdulilah was Salat wa Salam ala rasoolulah.
Allahu Alim. In the Name of Allah, I praise Allah and ask
for His Peace upon Muhammad, ameen. Allah Alone is The
All-Knower.
To continue: Once again, Muslims are circulating a
fabrication on the Internet trying to claim things which
can easily be proven incorrect by Christians and non-
Muslims who rejoice in watching us play the part of
Everyday Fools.
The most recent story says that Christians could not
conquer the Muslims there and sent spies to discover why.
According to the story, they found that the Muslims
there were on the 'Taqwah' (God Fearing and Pious) of
Islam. Then the story says the Christians sent in alcohol
and cigarettes which the Muslims used and lost their
'Taqwah' and then the Christians defeated the Muslims
on April first and began celebrating 'April Fool's Day' ever
since. This story is not correct in many aspects.
1.) First, let us consider the historic fact that Muslim
Spain ended on the 12th of January in the Christian
year of 1492 A.D. yet 'April Fool's Day was not heard of
until over fifty years later. Once upon a time, back in
16th-century France, before computers, people celebrated
New Year's Day on March 25, the advent of spring. It
was a festive time. They partied steadily until April 1. In
1564, when the calendar reformed and became Gregorian,
under the influence of Pope Gregory, King Charles IX
proclaimed, perhaps
pompously, that New Year's Day should be celebrated on
January 1st instead of in the spring. Diehard conservatives
resisted the change (or perhaps didn't hear about it due
to the absence of e-mail) and continued to celebrate
New Year's from March 25 to April 1. During this period
of spring festivity, the more flexible French mocked the
rigid revelers by sending them foolish gifts and invitations
to nonexistent parties. The victim of an April Fools' Day
prank was called a "poisson d'avril," or an "April fish,"
because at that time of year, the sun was leaving the
zodiacal sign of Pisces. April Fools' Day hit its stride
(avoiding the banana peel) in England in the 18th century,
and was brought to colonial America by the English,
Scottish, and French.
2.) Second, we should know that cigarettes were not
even invented until AFTER the time of the fall of Muslim
Spain (January 1492). According to the State College in
Framingham, the Human Biology course by Dr. Roger
Morrrissette, Ph.D., smoking of any kind did not exist in
Spain until after it was brought back from the New
World AFTER King Ferdinand and Queen Isabella had come
to rule Spain. This is from their website:
Introduction to Human Biology Framingham State College
Roger N. Morrissette, Ph.D.
I. The History of Smoking.
900: smoking is referred to on a Mayan stone carving.
1492: Columbus notes the natives of the New World
smoke leaves.
1550: Spaniards begin cultivating tobacco in the West
Indies to export to Europe.
1880: Tobacco use is widespread but people only use small
amounts.
3.) Muslim Spain began to deteriorate at the time of Ibn
Seenah and others who were beginning to use their logic
in place of Divine Revelation of Allah. Some were very
interested in the Greek and Roman philosophies and
concepts and began to try to 'rethink' Islam much the
same as some 'modernists' are doing today. It was right
after this that Muslim Spain began to divide up into small
kingdoms and fight against each other for control and gold.
They employed mercenaries from amongst the Christians
and killed and destroyed each other for a number of
years. When the Christians came against them the first
time, they appealed to the ruler of Maghrib (Morocco)
across the Mediterranean Sea who sent troops to quell
the attacks. He stipulated that the Muslims must stop
fighting each other and go back to the Islamic system of
rule under one leader. They did not do it. When they
began fighting each other again, the Christians came in
very strong against them and this time the ruler of
Morocco refused to help them. They lost battle after
battle against the Roman Christians and finally the last
stronghold of Islam fell to the Christian King, Ferdinand,
in January of 1492. [for details order the video "Muslim
Spain"]
So regarding the email claiming that April Fools Day is a
celebration of the take over of Muslim Spain, it is clear
the whole thing is a made up lie. This is totally
unacceptable and should be brought to the attention of
the one who sent you this lie in the first place. A good
Muslim would never accept to repeat lies and fabrications
especially in presenting facts about the history of Islam.
If you have received such a letter it is your duty in
front of Allah to write back to those who also received
it and ask them to contact all of those on their lists and
email the truth about this issue. And we should all fear a
Day when we will stand in front of Allah and be asked
about these matters.
If we don't do something about correcting the education
of our beloved brothers and sisters in Islam, then
everyday on the internet is MUSLIM FOOLS DAY.
Again, it is only Allah who has All Knowledge. May He
forgive me my mistakes and guide us all to the right way,
ameen
