Despite multiple concerns regarding the reliability of the origin of Islamic religion, most historians agree that Islam first originated in Saudi Arabia at the beginning of the 7th century. Although the origin of this religion is usually accredited to prophet Muhammad, according to the Quran Islam began even before Muhammad was born. The Quran testifies of itself that it was first given to angel Gabriel by God. Its angel Gabriel who later gave the Quran to Muhammad who then introduced it to the world in 610 A.D. after he began to experience what he claimed to be angelic visitations. Prophet Muhammad is said to have been born in Mecca around 570 and his family belonged to Quraysh tribe.
After receiving divine visions and revelations, Muhammad began teaching people around him about a monotheistic God and the impending Judgement Day. Although his teachings angered most businessmen who made their living from worshipping multiple idols, his teachings still gained him disciples as well as enemies in equal measure. The people of Mecca were involved in various polytheistic-cults that had gods who were thought to protect their lucrative businesses.
As more people continued to rally around him, Muhammad started to receive increasing resistance from the opposing elites of Mecca and after the death of influential uncle Abu –Talib in 618 A.D, he decided to move 200 miles north of Mecca to the city of Yathrib (currently known as Medina). His experience in business enabled him to join politics and he went ahead to become the head of an Islamic City/State in Saudi Arabia. Muhammad’s political move is known as the Hijara and it marks the beginning of the Islamic Era. As a political leader, he worked on uniting all the Arabic tribes under one religion, Islam.
More Arabs continued to join Islam and armies from Mecca came to attack Muhammad repeatedly in Medina without any success. Muhammad eventually invaded Mecca with his own army and conquered it. From here, he extended the Muslim-Rule in all of Arabia. By the end of the 8th century, Islamic-Empire had extended to Indus River on the East and Iberia on the West. The spread of Islam led to Islamic Civilization which gave rise to various cultural and scientific centers that produced renowned doctors, astronomers, philosophers and mathematicians in what is regarded as the Golden –Age of Islam.
