Who is Muhammad?
Muhammad (مُحَمَّد) was 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. Muhammad united Arabia into a single Muslim polity, with the Quran as well as his teachings (Hadith) and practices (Sunnah) forming the basis of Islamic religious belief.
The name Muhammad means “praiseworthy” and appears four times in the Quran. The Quran addresses Muhammad in the second person by various appellations; prophet, messenger, servant of God (‘abd), announcer (bashir), witness (shahid), bearer of good tidings (mubashshir), warner (nathir), reminder (mudhakkir), one who calls [unto God] (dā’ī), light personified (noor), and the light-giving lamp (siraj munir).
