Chapter I
Muhammad ibn ‘Abdullāh (Arabic: ﷴ; Transliteration: Muḥammad;[2] pronounced [mʊˈħæmmæd] ( listen); also spelled Muhammed or Mohammed)[3][4][5] (ca. 570/571 Mecca[مَكَةَ ]/[ مَكَهْ ] – June 8, 632),[6] was the founder of the religion of Islam [ إِسْلامْ ] and is regarded by Muslims as a messenger and prophet of God (Arabic: الله Allāh), the greatest law-bearer in a series of Islamic prophets and by most Muslims the last prophet as taught by the Qur'an 33:40–40. Muslims thus consider him the restorer of an uncorrupted original monotheistic faith (islām) of Adam, Noah, Abraham, Moses, Jesus and other prophets.[7][8][9] He was also active as a diplomat, merchant, philosopher, orator, legislator, reformer, military general, and, according to Muslim belief, an agent of divine action.[10]
Born in 570 in the Arabian city of Mecca,[11] he was orphaned at an early age and brought up under the care of his uncle Abu Talib. He later worked mostly as a merchant, as well as a shepherd, and was first married by age 25. Discontented with life in Mecca, he retreated to a cave in the surrounding mountains for meditation and reflection. According to Islamic beliefs it was here, at age 40, in the month of Ramadan, where he received his first revelation from God. Three years after this event Muhammad started preaching these revelations publicly, proclaiming that "God is One", that complete "surrender" to Him (lit. islām) is the only way (dīn)[12] acceptable to God, and that he himself was a prophet and messenger of God, in the same vein as other Islamic prophets.[9][13][14]
Muhammad gained few followers early on, and was met with hostility from some Meccan tribes; he and his followers were treated harshly. To escape persecution first Muhammad sent some of his followers to Abyssinia before he and his remaining followers in Mecca migrated to Medina (then known as Yathrib) in the year 622. This event, the Hijra, marks the beginning of the Islamic calendar, which is also known as the Hijri Calendar. In Medina, Muhammad united the conflicting tribes, and after eight years of fighting with the Meccan tribes, his followers, who by then had grown to ten thousand, conquered Mecca. In 632, a few months after returning to Medina from his Farewell pilgrimage, Muhammad fell ill and died. By the time of his death, most of the Arabian Peninsula had converted to Islam; and he united the tribes of Arabia into a single Muslim religious polity.[15][16]
