Their fight with him, as most fights in this world are, was mostly about wealth, power, position, status, conceit, arrogance, ego, race, revenge, personal leadership, land and tribal domination.
So, when they finally lost their fight against truth and against reason, and the Prophet, Sallallahu Alaihi wa Sallam, gave them their freedom and security back, they had nowhere to go but to Islam.
They willingly and voluntarily converted to Islam in wave upon wave.
Thus, it was not violence and force that got them to covert to Islam, but Islam's basic rationality on the one hand and the Prophet's, Sallallahu Alaihi wa Sallam, kindness, compassion, generosity and forgiveness on the other hand.
Islam in Practice III:
Khalifah Umar Takes Control of Jerusalem from the Christian Priests
Jerusalem was under the control of Pope's Christian followers. They sent word to Khalifah Umar that if he came personally to Jerusalem, and if they found him to be the right man, they will throw open the gates of the city to him without a fight.
Umar came riding on a camel, which he took turns sharing with his slave. As master and slave approached the gates of Jerusalem, it was the slave's turn to ride the camel, while Umar, the Ruler, walked along side on foot.
The Christian priests of the Holy Land saw this divinely designed super-human spectacle of human equality with their own eyes. They needed no further proof of who Umar really was and what he stood for.
Those were the days when truth and honesty and integrity were still the hallmarks of "religion" in most instances. So, Umar personally took control of the holy city without shedding a drop of blood.
Later, as the prayer time approached, the priests asked Umar to perform his "prayers" inside the church, Umar excused himself saying: "If I do my prayers inside the church, some day the Muslims may demand control of the church. So, it is better I do my prayers outside."
Another proof to the priests of Jerusalem what kind of a man Umar, this follower of the Prophet, Sallallahu Alaihi wa Sallam, really was and what kind of a message and faith he represented.
Islam Spread Based on Merit,
Not Based on Force
Ask yourself this:
Wouldn't you want to be a part of a system that taught the most wonderful things in life; that offered a most rational model of God and his relationship to your own life; that offered all human beings, regardless of race or gender, a wonderful life of dignity, freedom and equality on earth; that offered them a fair and equal chance of salvation and bliss in the next life based on their own beliefs and behavior in this life; and that showed you in practice how to make your life better on earth, while making it also better in the next life?
Wouldn't you say to yourself, especially if you had been denied all these things all your life - and for centuries:
"You mean there really is a system like that somewhere? Unbelievable!
Let me check this Islam out. It sure seems to make a lot of sense.
And it sure looks like the thing I can use to make my life better?"
That is what you are likely to say yourself. And that is precisely what a lot of people in the world ended up saying.
And that is also precisely what is happening to a lot people even now - even as all kinds of lies, distortions and propaganda are let loose against Islam and the Prophet, Sallallahu Alaihi wa Sallam.
Islam Spread because Islam Had
Reason and Logic on Its Side
So, Islam spread because it made more sense; because it had reason and logic on its side; and because it offered everybody an opportunity to a better life.
For the first time in their life a lot of people saw an opportunity for personal dignity and freedom and for human equality and justice. And for the first time in their life they came face to face with a system whose teachings made a lot of sense to them. A system that seemed to have more reason in its teachings than the usual religious mumbo-jumbo they were used to throughout their lives.
It were these superhuman examples of equality, honesty, generosity, justice and compassion on the one hand and of basic rationality and simple elegance on the other hand that won converts to Islam by the droves, not Muslims running around with swords in their hands, forcing people to accept Islam or die.
The sword theory was a vicious lie that was invented by the Pope's Christian followers to stem the tide of Islam from sweeping Europe as it had swept other parts of the world.
And it is pretty much the same thing happening now, as Islam is once again knocking at the gates of Europe and the West in the form of a rising tide of Muslim immigrants and local converts from Christianity.
Islam in Practice IV:
Saladin's Magnanimous Treatment of the Crusader Followers of the Pope
The then Pope had personally rallied his followers to go to Jerusalem and drive out the "infidel" Muslims and kill them. The Pope's Christian followers blazoned a trail of violence, blood and barbarity wherever they went.
The Crusaders even found it necessary to subject Jewish populations along the way to the usual Christian cruelty and inhumanity that had characterized Jewish-Christian relations for centuries.
They drenched the soil of the Holy Land in rivers of blood so deep their horses sank up to their knees in human gore.
Then along came Saladin, the Muslim follower of the Prophet, Sallallahu Alaihi wa Sallam. Saladin defeated the Crusaders and expelled them from the Holy Land. But in doing so he took a leaf directly out of the book of the Prophet, Sallallahu Alaihi wa Sallam, at Makkah.
