No! Neither Islam nor Christianity are a sword religion, because there can be no compulsion in religion. However, if religion becomes a tool of exploitation and oppression, then it becomes a sword religion.
Allah sent Prophet Muhammad as the final messenger, and this is clear evidence that Islam is not religion that is inherited. He lost his father before his birth, his mother at six and his grandfather at eight. He was destined to grow up an orphan, raised by his uncle and aunt. He was calm, quiet, polite and tranquil man. When it was revealed that he was the prophet on Mt. Noor, he was not overly pleased. Instead, he was frightened and  worried. Yet, it was not up to him. He had been sent as a prophet to all of humanity. His mission began in Mecca. His first believer was his beloved wife,  Khadija. Then came Abu Bakr, Ali, Zaid, Uthman, Abd-ar-Rahman, Talha, Sa'd and Zubair. His ummah consisted of nine people, one woman and eight men. These companions were the first believers and the pioneers of Muslims in the hardest times. May Allah be pleased with them.
Prophet Muhammad first delivered his messages in secrecy. When he was ordered to deliver his message in public, he began to do so and caused a shock in Mecca.
The rulers of Mecca fiercely attacked him so that they could keep their positions and their regimes, which were based on idolatry. They insulted Prophet Muhammad and tortured newly converted Muslims.  However, the tree of Islam planted by Prophet Muhammad began to produce fruit.
Although the rulers of Mecca increased their pressure, the numbers of Muslims also increased. Islam also spread among the tribes outside of Mecca.
Six people from Medina became Muslims in Aqaba after they met with Prophet Muhammad. Thus, Islam began to spread in Medina. Soon, most of the people in this city had converted to Islam and they invited Prophet Muhammad to their city. Prophet Muhammad accepted their invitation and the Muslims emigrated from Mecca to Medina. A new era began after Prophet Muhammad entered into Medina. Muslims passed from being a congregation to a state and the first Islamic state was established.
Beginning with a single person in Mecca, in 13 years Islam had moved to Medina and a new era had now begun. During that period, Prophet Muhammad had not wielded a needle, lest alone sword.  All the converts had come to Islam by free will.
Founding a state or declaring independence is easier than maintaining independence or preserving the state. It was very difficult for the Islamic state, founded in a small city placed on the Arabian Peninsula, to sustain independence in the conditions of that time. The Islamic state was surrounded by hostile Jewish tribes, like the Banu Nadir, the Banu Quraiza and the Banu Qainuqa, and hostile pagan tribes headed by the Meccans.
Neighboring tribes attacked Medina, taking animals and abducting people to sell in slave markets. It was necessary to maintain security in order for the Islamic State to survive not only in and around Medina, but also in the Arabian Peninsula.
Allah Almighty says:
“There is no compulsion in religion.” (Al-Baqara, 256)
Yes, there is no compulsion in the religion. People cannot be converted to Islam by force or intimidation. However, war is permissible to ensure the security of life and independence, which is the first priority of states.
When the Meccan pagans could not win in the battles of Badr and Uhud, they prepared an army of 10,000 men, consisting of Jews and pagans under the command of Abu Sufyan in the fifth year of the Hijrah. They marched against Medina to kill Prophet Muhammad and all the Muslims.
The Muslims dug deep trenches as a barrier against the invaders along the open parts of Medina, and engaged in a defensive battle using arrows and stones.
It was winter and cold. Furthermore, the Muslims' food stocks were exhausted.
As the battle developed, it did not go the way the pagans desired. They unsuccessfully tried to cross the trenches and wasted thousands of arrows for nothing.
At the time of the afternoon prayer on the last day of the battle, Archangel Gabriel came and informed the Muslims that the pagans would withdraw and that this the final attack of the Meccans against Medina.
In the evening a violent sandstorm accompanied by terrifying sounds came down on the camp of the Meccans.
This wind upset their cooking-pots and knocked over their tents. The animals rushed madly into their riders, their eyes burning with sand. The pagans, too, were made uneasy by the wind and could not see one another.
As the air darkened, the angels came to help and uttered the words “Allah-u Aqbar” in a roaring voice. The pagans were frightened and ran away.
The Battle of the Trench was the final defensive battle of the Muslims in Medina. After this battle, a period of conquests began. The Islamic State enlarged and conquered many places by the will of Allah Almighty.
The defeat of an army of 10,000 men was an important message for the enemies of the Muslims. Indeed, the Arab tribes understood this message very well and now paid attention to Islam. They sent committees to Medina and soon began to convert to Islam.
The Conquest of Mecca
The most important event in the era of Prophet Muhammad was the conquest of Mecca, because Mecca, the city of the Ka'ba, was the center of all the tribes that were opposed to Islam. Since the time of the attack of Abraha (before Prophet Muhammad was born) the importance of Mecca and Ka'ba had been well recognized.
The pagans in Mecca believed that if a Muslim army attempted to attack Mecca, its fate would be similar to that of the army of Abraha, which had been destroyed. The conquest of Mecca would actually be the conquest and Islamization of the Arabian Peninsula.
In the eighth year of the Hijrah, Prophet Muhammad surrounded Mecca. He headed an army of 10,000 men, all of whom were volunteers.
Before marching, he ordered his commanders not to attack anyone before they attacked and to avoid bloodshed.
He also sent a message to the people of Mecca, guaranteeing the lives of those who did not participate in the war, either entering the house of Abu Sufyan or the Ka'ba, or laying down arms, and locking their doors.
The Meccan pagans assumed that Prophet Muhammad would take revenge in return for what they had done, and therefore were fearful and anxious about what would happen.
When the conquest was completed accompanied by chants of takbir, Prophet Muhammad stood at the door of the Ka'ba and declared: “This day there is no reproof against you. Go your way, you are free...”
The Meccan people received this declaration with great joy and applause. They blamed themselves, since they had attributed bad names to Islam and Prophet Muhammad; they now began to convert o Islam.
Prophet Muhammad forgave the people of Mecca, who had been the greatest enemies of Islam, without condemning or punishing the, only stipulating that they should become Muslims. This was a manifestation of the personality of Prophet Muhammad and the essence of Islam. It is also clear proof that Islam is not a sword religion.
The Middle Ages were a time of darkness. People were without hope and unhappy. Those who were oppressed and mistreated yearned for a savior. They were humans and they had the right to live as humans.
As Allah had predestined, the Muslim armies came to rescue these oppressed people from the dictators. Those who had once perceived the Muslim armies as occupying forces and who had fought against them with dictators were perplexed by the good manners of Muslims. There was no discrimination in Islam on the basis of race, color or language. The poor and the rich, the boss and the worker were all equal. A slave could sit down with a noble of Quraiysh, they ate together and prayed in the same rank.
The Muslims did not exploit the places they conquered nor did they enslave people. Instead, they lifted the heavy taxes stipulated by dictators and issued a minimum tax called the jizya.
According to the order of Allah that there is no compulsion in the religion, no one was forced to convert to Islam. Yet, those who became acquainted with Islam and the Muslims voluntarily converted to Islam. Thus, the Islamic city state was transformed into a world state in a short time. If the Muslim armies had acted like occupying forces, shedding blood and compelling people to convert to Islam, then they would have faced intense resistance and probably would have failed with only a small group of Medina soldiers.

The year was 614 - A Persian army had conquered Jerusalem. Christian men, women and children, including those who had taken refuge in the churches, were killed. Churches were destroyed.
The year was 638 – Jerusalem was surrounded by Muslim army. The city surrendered to Caliph Umar without resistance. People were terrified, assuming that the horrific massacre committed 24 years before would happen again.
Umar proposed a treaty, saying that the people of Jerusalem were under the protection of Islam and that they were free and safe in their souls, their property, their churches, their crosses, the sick and the healthy, and their whole community.
He also lifted the heavy taxes stipulated by the Byzantines and issued a reasonable tax, the jizya.
Soon, the people of Jerusalem voluntarily began to convert to Islam.
The year was 1099 – Jerusalem was captured by the Crusaders. The Crusaders killed Muslim and Jewish inhabitants, including women, children, the sick and the poor - a total of 70,000. The streets of Jerusalem were full of dead bodies and blood.
The Crusades, the bloodiest religious wars in history, were eight wars originally sanctioned by Pope Urban II in the name of Christianity that continued from 1096-1270. The Crusades damaged not only the Muslims, but also the Jews and the Byzantines, who were Christians. Many places were sacked and millions of people were killed.

The year was 1453 – On 29 May, a Tuesday, after the morning prayer, the Ottoman army entered Constantinople. The Byzantines were scattered around and most of them took refuge in Hagia Sophia. At noon, Sultan Mehmet, the Conqueror, along with his commanders and his teacher, entered the city from the gate of Topkapi and went to Hagia Sophia. Hagia Sophia was full of Byzantines, women and men, and they were crying loudly. Sultan Mehmed first prayed to thank Allah and then declared: “Stand up and do not cry! You have freedom in your religion and worship and you all are safe and secure.”

The year was 1492 – The Christians attacked the most beautiful mosque in the world, the Qartaba after defeating the Andulus State. They entered the mosque on horsebacd. They killed all the Muslims who had taken refuge in the mosque. They threw down the original copy of Qur'an that dated from the time of Claph Uthman and trampled upon it.
The Muslims and Jews in the Qartaba were forcibly converted to Christianity.
Bernard Shaw, a British writer, said:
“If there were only one religion for the world it would be Islam. Islam is the only religion, which can be adapted to every century. I predict that Islam will be the religion which will be accepted by tomorrow’s Europe.”
My dear readers!
Today's Bibles, which are dependent on dreams, legend and the testimonies of witnesses, are certainly the word of man. Since they cannot satisfy Europe in the present or in the future, by the will of Allah, the Europeans will accept Islam.
The fundamental basis of all true religions is unity, which is the belief that there is no god but Allah.
Those who associate a son to Allah are no different from those who worship idols.
Once, people worshipped the sun and moon. Today, this belief has no basis at all. Likewise, the legend that Prophet Jesus is the son of Allah and that Allah sacrificed His only son to save humanity is baseless. The baby lion, after growing up, becomes a mature lion and lives freely in the forests. A baby human, after growing up, becomes a mature human and lives freely. If Prophet Jesus were the son of Allah, he would become God (!) and create a new universe composed of hundreds of galaxies instead of dealing with only a few Jews in this small world.
