Muhammad relative Alī ibn Abī Ṭālib
Opposition
According to Muslim tradition, Muhammad's wife Khadija was the first to believe he was a prophet. She was followed by Muhammad's ten-year-old cousin Ali ibn Abi Talib, close friend Abu Bakr, and adopted son Zaid. Around 613, Muhammad began to preach to the public. Most Meccans ignored and mocked him, though a few became his followers. There were three main groups of early converts to Islam: younger brothers and sons of great merchants; people who had fallen out of the first rank in their tribe or failed to attain it; and the weak, mostly unprotected foreigners.According to Ibn Saad, opposition in Mecca started when Muhammad delivered verses that condemned idol worship and the polytheism practiced by the Meccan forefathers. However, the Quranic exegesis maintains that it began as Muhammad started public preaching. As his followers increased, Muhammad became a threat to the local tribes and rulers of the city, whose wealth rested upon the Kaaba, the focal point of Meccan religious life that Muhammad threatened to overthrow. Muhammad's denunciation of the Meccan traditional religion was especially offensive to his own tribe, the Quraysh, as they were the guardians of the Kaaba. Powerful merchants attempted to convince Muhammad to abandon his preaching; he was offered admission to the inner circle of merchants, as well as an advantageous marriage. He refused both of these offers.After Muhammad
Muhammad united several of the tribes of Arabia into a single Arab Muslim religious polity in the last years of his life. With Muhammad's death, disagreement broke out over who his successor would be. Umar ibn al-Khattab, a prominent companion of Muhammad, nominated Abu Bakr, Muhammad's friend and collaborator. With additional support Abu Bakr was confirmed as the first caliph. This choice was disputed by some of Muhammad's companions, who held that Ali ibn Abi Talib, his cousin and son-in-law, had been designated the successor by Muhammad at Ghadir Khumm. Abu Bakr immediately moved to strike against the Byzantine (or Eastern Roman Empire) forces because of the previous defeat, although he first had to put down a rebellion by Arab tribes in an event that Muslim historians later referred to as the Ridda wars, or "Wars of Apostasy".The pre-Islamic Middle East was dominated by the Byzantine and Sassanian empires. The Roman–Persian Wars between the two had devastated the region, making the empires unpopular amongst local tribes. Furthermore, in the lands that would be conquered by Muslims many Christians (Nestorians, Monophysites, Jacobites and Copts) were disaffected from the Eastern Orthodox Church which deemed them heretics. Within a decade Muslims conquered Mesopotamia, Byzantine Syria, Byzantine Egypt, large parts of Persia, and established the Rashidun Caliphate.
