Most of the non-Muslims believe that Islam spread all over the world due to the use of the force. But it is wrong, that Islam spread all over the world by the sword, it spread due to the force of truth, logic and reasons.

The religion Islam has given due respect to all the religions of the world and gives freedom to people to choose right path for their selves. As Allah Almighty says in the Quran about the freedom of religion: "There shall be no compulsion in [acceptance of] the religion. The right course has become clear from the wrong." (Quran 2:256)

One of the famous historians, De Lacy O’Leary wrote in his book ‘Islam at the Crossroads’, "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 myths that historians have ever repeated.”

Another famous historian, Thomas Carlyle, wrote in his book ‘Heroes and Hero Worship’ about the spreading of Islam in these words: "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 tries 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."

Islam was spread by the sword of intellect and the convincing arguments. The teachings of the Quran and Islam won the hearts and the minds of the people. Allah Almighty says in the Holy Quran that: "Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best." (Quran 16:125)
Indonesia is the country which has largest number of Muslim population all around the world, and a large number of people are Muslims in Malaysia. But, do you ever listen that any Muslim army entered in both the countries and force the people to be Muslim. It is an open fact that Indonesia entered in Islam not because of war or any other type of pressure, but it is due to its moral message and the teachings of the Quran and Islam. There are also some countries in the world where once Muslims ruled but now they are under the control of some other nations.

· It is one the historical facts that, Muslims ruled the Spain for about 800 years and during the reign of Muslim rulers, Christians and Jews enjoyed their religious practices freely.
· Muslims ruled over the India for about one thousand years but they never tried to force them to convert to Islam.

In the end, it is said that Islam spread all over the world due to the force of truth and not due to the sword. There are lots of countries in the world where Muslims once ruled but now they are in minorities. In America and Europe, Islam is the only fastest growing religion.
