Muhammad (or Mohammad, Mohammed, Arabic: محمد) (c. 26 April 570 – 8 June 632) was the founder of the religion of Islam. He is considered by Muslims to be a messenger and prophet of God, and the last law-bearer in a series of Islamic prophets. Most Muslims consider him to be the last prophet of God as taught by the Quran. Muslims thus consider him the restorer of an uncorrupted original monotheistic faith (islām) of Adam, Noah, Abraham, Moses, Jesus and other prophets.
Born in 570 in the Arabian city of Mecca, 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) acceptable to God, and that he himself was a prophet and messenger of God, in the same vein as other Islamic prophets.
Muslims identify the Prophets of Islam (Arabic: النبوة في الإسلام) (Persian: پیامبران در اسلام) as those humans chosen by God and given revelation to deliver to mankind. Muslims believe that every prophet was given a belief to worship God and their respective followers believed it as well. Each prophet, in Muslim belief, preached the same main belief of worshiping God (which in Arabic is translated as Allah) and in the avoidance of idolatry and sin. Each came to preach Islam at different times in history and some, including Jesus, told of the coming of the final prophet and messenger of God, who would be named Muhammad. Each prophet directed a message to a different group of people, and thus would preach Islam in accordance with the times. Although many lay Muslims and many Western scholars and writers hold the view that Islam began with Muhammad in Mecca, this contradicts the Quran, which says that Muhammad simply was the last prophet who preached the same faith that Adam preached to his children.
Islamic tradition holds that God sent messengers to every nation. Muslims believe that God finally sent Muhammad to transmit the message of the Quran, the holy book which, according to Islam, is universal in its message. The reason the Muslims believe the Quran is universal and will remain uncorrupted is because they believe that previous Islamic holy books, namely the Torah given to Moses; the Psalms given to David; and the Gospel given to Jesus, were for a particular time and community and because they believe that, even if the books were corrupted, many prophets were still to come who could tell the people of what was correct in the scripture and warn them of corruptions. Muhammad therefore, being the last prophet, was vouchsafed a book which, in Muslim belief, will remain in its true form till the Last Day.
