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 anti-social 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%u2019Leary.
The best reply to the misconception that Islam was spread by the sword is given by the noted historian De Lacy O%u2019Leary 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.
