Buddhism in the period when Sakyamuni founded Buddhism and his disciples successively preached Buddhism. Around the 5th century BC. At first, the Buddha's sermon was passed on by mouth. In order to facilitate memory, it took the form of ode, and later it was compiled into Sanzang, which was composed of classics, laws and theories. Among the classics and collections, modern scholars believe that the earliest classics that truly belong to the teachings and theories of the Buddha are The Collection of Classics, Confucian Classics, and Wu Wen Jing, which also include some commandments. The basic teachings of primitive Buddhism are "four truths", "eight right paths" and "twelve causes", and its core content is to talk about suffering in the real world and the methods to solve it. Secondly, from the original thought, the theories of "all behaviors are impermanent", "all laws have no self" and "Nirvana is silent" are put forward. Later, the practice of primitive Buddhism was summarized as three studies of precept, determination and wisdom, four boundless minds of sadness and joy, and thirty-seven bodhi points such as four thoughts, four righteousness, four holy feet, five roots, five powers and seven senses. When the Buddha was alive, he opposed the unequal fourth-class caste system in Brahmanism. Therefore, all castes and untouchables are allowed to join the monk group he founded. In addition, it is also allowed to include male and female believers who have lived at home, called Youposai, Youpoyi, or two people at home.

Christianity is the most widely spread religion with the largest number of followers in the world today. Christianity was born in Palestine on the Mediterranean coast in the middle of the 1st century A.D. It split from Judaism in 135 and became an independent religion. In 392, Christianity became the state religion of the Roman Empire and gradually became the main spiritual pillar of medieval European feudal society. 1054, Christianity split into Roman Catholicism and Greek Orthodox Church. /kloc-In the middle of the 6th century, the Catholic Church had a religious reform movement, and some new sects broke away from the Roman Catholic Church, collectively known as Protestantism, also known as anti-Romanism or Protestantism, and were called Jesuits in China. Therefore, Christianity is the collective name of Catholicism, Orthodox Christianity and Protestantism.

The founder of Christianity is Jesus. Jesus, the son of God, was born in Nazareth, Galilee, in northern Palestine. His mother's name is Mary and his father's name is Yue Se. Before Mary got married, the Holy Spirit descended on her and got her pregnant. Yue Se once wanted to divorce Maria, but the angel instructed him to marry her. At the age of thirty, Jesus was baptized by John and tempted by Satan in the wilderness, which strengthened his belief in God. After that, Jesus led Peter, John and other disciples to spread the gospel everywhere. Jesus' preaching caused panic among Jewish nobles and priests, who bought Judas, Jesus' disciple, and crucified Jesus. But three days later, Jesus came back to life and showed signs to his disciples and the masses, asking them to preach the gospel on a larger scale. Since then, more and more people believe in Christianity, and they spread Christianity all over the world.

The classic of Christianity is the Bible. What is recorded in the Bible is the revelation of God, the general program of Christian faith and the principle of life, and the eternal truth. The Bible is divided into two parts: the New Testament and the Old Testament. The Old Testament was originally a classic of Judaism. Jesus put forward his own views on some aspects different from Judaism, and explained them as an important basis for his beliefs. The Old Testament includes Torah, Prophet, History Book and Miscellany, with a total of 39 volumes, which records the origin of heaven and earth, the origin and history of Jews and the literary works of ancient Jews. The New Testament includes the gospels (Matthew, book of kells, Luke and John), history books, apostles' letters and revelations, with a total of 27 volumes, in which the words and deeds of Jesus and his disciples are mainly described. In the book of revelation, the doomsday prophecy of Christianity is also described.

Islam is one of the three major religions in the world alongside Buddhism and Christianity. Born in Arabia in the 7th century. It was created by the Prophet Muhammad of Islam. At present, there are more than 654.38 billion followers in the world, most of whom are located in Arab countries, as well as Central Africa, North Africa, Central Asia, West Asia, Southeast Asia, India, Pakistan and China. Some countries still regard Islam as the state religion.

Islam was born in the period of great social change in Arabian Peninsula. The quartet is divided and wars are frequent. There are internal and external troubles, and there are many crises. In religious belief, primitive religion prevails, people worship natural objects, and each tribe has its own god. At the same time, Judaism and Christianity began to spread to the peninsula, but their theories were not suitable for this situation. Therefore, achieving peaceful reunification of the peninsula and social peace is the way out for Arab society. At this time, the prophet Muhammad appeared. With the slogan "Allah is the only true God", he put forward the ideas of prohibiting usury, "giving alms to help the poor" and "peace and tranquility", which reflected the demands of the society at that time. Islam was born at such a turning point.

Islam believes that there is no god except Allah and opposes polytheism and idolatry. Islam is a transliteration of Arabic, which means "obedience". People who obey God's will, that is, "submissive", are called "Muslims" in Arabic, which is a general term for Muslims. In China, Muslims also call God "Huda" or "Allah". Muslims believe that Muhammad is a "prophet" and a "messenger of God", who preaches Islam to mankind under the orders of God. The history of Islam has been nearly 1400 years since Muhammad began to preach. Muslims all over the world are distributed in more than 90 countries and regions, but no matter where they are, Muslims call each other brothers, or "Dosti", and greet each other when they meet. In Arabic, it means "Ansel Muir came to Qom", which means "May God grant you peace", and the answer is "Baye Qom Muir", which means "May God grant you peace".

From the beginning of the 7th century to the 17th century, a series of dynasties and empires, large and small, such as Umayyad Dynasty, Abbasi Dynasty, Mughal Dynasty in India and Ottoman Empire in Turkey, were established in the name of Islam. With the changes of the times, these prosperous dynasties have become historical relics, but "Islam" as a world religion has never fallen; It has changed from a nation's religion to the spiritual source of an empire, and then it has become a religious, cultural and political force, a way of life for people, and it has been developing continuously all over the world.
