WAS ISLAM SPREAD BY THE SWORD?
Question:
How can Islam be called the religion of peace when it was spread by the sword?
Answer:
It is a common complaint among some non-Muslims that Islam would not have
millions of adherents all over the world, if it had not been spread by the use of
force. The following points will make it clear, that far from being spread by the
sword, it was the inherent force of truth, reason and logic that was responsible
for the rapid spread of Islam.
1. Islam means peace.
Islam comes from the root word ‘salaam’, which means peace. It also means
submitting one’s will to Allah (swt). Thus Islam is a religion of peace, which is
acquired by submitting one’s will to the will of the Supreme Creator, Allah (swt).
2. Sometimes force has to be used to maintain peace.
Each and every human being in this world is not in favour of maintaining peace
and harmony. There are many, who would disrupt it for their own vested
interests. Sometimes force has to be used to maintain peace. It is precisely for
this reason that we have the police who use force against criminals and antisocial
elements to maintain peace in the country. Islam promotes peace. At the
same time, Islam exhorts it followers to fight where there is oppression. The
fight against oppression may, at times, require the use of force. In Islam force
can only be used to promote peace and justice.
3. Opinion of historian De Lacy O’Leary.
The best reply to the misconception that Islam was spread by the sword is given by
the noted historian De Lacy O’Leary in the book “Islam at the cross road” (Page 8):
“History makes it clear however, that the legend of fanatical Muslims sweeping
through the world and forcing Islam at the point of the sword upon conquered races
is one of the most fantastically absurd myth that historians have ever repeated.”
4. Muslims ruled Spain for 800 years.
Muslims ruled Spain for about 800 years. The Muslims in Spain never used the
sword to force the people to convert. Later the Christian Crusaders came to
Spain and wiped out the Muslims. There was not a single Muslim in Spain who
could openly give the adhan, that is the call for prayers.
5. 14 million Arabs are Coptic Christians.
Muslims were the lords of Arabia for 1400 years. For a few years the British
ruled, and for a few years the French ruled. Overall, the Muslims ruled Arabia
for 1400 years. Yet today, there are 14 million Arabs who are Coptic Christians
i.e. Christians since generations. If the Muslims had used the sword there would
not have been a single Arab who would have remained a Christian.
6. More than 80% non-Muslims in India.
The Muslims ruled India for about a thousand years. If they wanted, they had
the power of converting each and every non-Muslim of India to Islam. Today
more than 80% of the population of India are non-Muslims. All these nonMuslim
Indians are bearing witness today that Islam was not spread by the
sword.
7. Indonesia and Malaysia.
Indonesia is a country that has the maximum number of Muslims in the world.
The majority of people in Malaysia are Muslims. May one ask, “Which Muslim
army went to Indonesia and Malaysia?”
8. East Coast of Africa.
Similarly, Islam has spread rapidly on the East Coast of Africa. One may again
ask, if Islam was spread by the sword, “Which Muslim army went to the East
Coast of Africa?”
9. Thomas Carlyle.
The famous historian, Thomas Carlyle, in his book “Heroes and Hero worship”,
refers to this misconception about the spread of Islam: “The sword indeed, but
where will you get your sword? Every new opinion, at its starting is precisely in
a minority of one. In one man’s head alone. There it dwells as yet. One man
alone of the whole world believes it, there is one man against all men. That he
takes a sword and try to propagate with that, will do little for him. You must get
your sword! On the whole, a thing will propagate itself as it can.”
10. No compulsion in religion.
With which sword was Islam spread? Even if Muslims had it they could not use
it to spread Islam because the Qur’an says in the following verse:
