Muhammad[n 1] (Arabic: مُحمّد, pronounced [muħammad];[n 2] c. 570 CE – 8 June 632 CE) was an Arab religious, social and political leader and the founder of Islam. According to Islamic doctrine, he was a prophet, sent to present and confirm the monotheistic teachings preached previously by Adam, Abraham, Moses, Jesus, and other prophets. He is viewed as the final prophet of God in all the main branches of Islam, though some modern denominations diverge from this belief.[n 3] Muhammad united Arabia into a single Muslim polity, with the Quran as well as his teachings and practices forming the basis of Islamic religious belief. He is referred to by many appellations, including Messenger of Allah, The Prophet Muhammad, Allah's Apostle, Last Prophet of Islam and others; there are also many variant spellings of Muhammad, such as Mohamet, Mahamad, Muhamad and many others.
The revelations (each known as Ayah — literally, "Sign [of God]") that Muhammad reported receiving until his death form the verses of the Quran, regarded by Muslims as the verbatim "Word of God" on which the religion is based. Besides the Quran, Muhammad's teachings and practices (sunnah), found in the Hadith and sira (biography) literature, are also upheld and used as sources of Islamic law (see Sharia).
The name Muhammad (d/) means "praiseworthy" and appears four times in the Quran. The Quran also addresses Muhammad in the second person by various appellations; prophet, messenger, servant of God ('abd), announcer (bashir),[2:119] witness (shahid),[33:45] bearer of good tidings (mubashshir), warner (nathir),[11:2] reminder (mudhakkir),[88:21] one who calls [unto God] (dā'ī),[12:108] light personified (noor),[05:15] and the light-giving lamp (siraj munir).[33:46]
