The followers of the prophet Jesus, who lived 570 years before Muhammad (pbuh), came to be known as Christian. People began to worship Jesus. Many different sects emerged, and his message became distorted. Muslims therefore believe that it was necessary as preached be Abraham, Moses, and Jesus could again be followed by believers. Muhammad (pbuh) was that person. At that time the saying of Jesus changed so then new religions arisen like Christianity (3). Muslims believe Jesus was a Prophet not the son of God.
Muslims believe that Muhammad (pbuh) is the last prophet and that the message revealed to him is God's final word to humanity. In the nineteenth century Mirza Golom Ahmad of Quadin in India (now part of Pakistan) claimed to be a prophet (3). Orthodox Islam cannot accept this view on recognize his followers to be Muslims, even though they use the Qur'an as their holy book.
This is why today there is more than one religion. Islam was supposed to be the only religion. What Jesus said is different from they say today. His sayings changed over the years. There have also been fake prophets to. They want to be fake prophets so that people will worship them or make people change their religion. That is why their followers are wrong and so are they.
The Qur'an invites all human beings to accept Islam. To whose do not accept it, the Qur'an tells Muslims to say "To you your religion, and me to my religion!" (Qur'an, 109:6). In other words, the Qur'an instructs Muslims to tolerate and give freedom to each individual to have his or her own faith” (4). It means to not make fun of other religions and tolerate it. It invites everyone to follow the path of Islam though you don't need to follow the patch of Islam.
The history of Muslim rule in the world also tells us that Jews, Christians, Hindus, Buddhists and followers of all our religions were allowed to practice their faiths. They were allowed to have their own schools and publish their own literature. There was no imposition of nationally determined curricula and textbooks. The main reason for this was that there was no concept of nationalism. People belonged to their respective religious groups and to tribes and races. The situation is more complicated today we are suppose to belong first to a particular nation and then to a religious or other religious groups (4). Muslim communities and cities allowed other religion to practice their faith. They had the same freedoms as Muslims.
Muslims do no make fun of other religions or do anything to upset them. Muslims tolerate all religions. Muslims are people who respect other people and their religion. We treat them the same way we want them to treat us. We give them respect. Even Muslim cities make laws so that it benefits all. Muslims treat other people the same way we treat people in our religion.
Hijrah and the Islamic State
In 620CE, six leading members if the Khazraz tribe of Medina became Muslim. The next year, five of these and seven other leading members came from Hajj (pilgrimage) and entered into on agreement with Muhammad (pbuh). They agreed to obey none but Allah, not to steal, commit adultery, kill children or disobey him. This agreement came to be known as the first covenant of Al-'Aqaba. The Prophet sent one of his companions, Musa Bin "Umair, to teach them the Qur"an and give the religious instruction. It helped the leaders become Muslim. It helped them become Muslim (Ashraf 21). They followed Qur'an teachings.
The Prophet then prepared to go to Medina; he discussed this with his uncle Abass who joined him the following year at "Aqaba where they held a secret meeting with members of the Khazraz tribe and some of the Aws tribe. They pledged to take Muhammad (pbuh) and protect him. Then they asked, "Tell us O Prophet of Allah, what will be our reward if we remain true to our oath?' The Prophet said, "Paradise". Then one by one they took a hold of his outstretched hand and promised to protect him. The Prophet had already promised to never leave them. Muhammad (pbuh) is saying that when you die you will go to heaven or paradise (21). So the people promise to follow Allah's laws.
When the leaders become a particular religion so everyone under them also become the same religion. When the King is Muslims then so are the peasants that are how it usually goes. If you do good deeds then you will be rewarded when you die. When you die then the reward you get will be that you will be able to go to heaven.
