Muhammad (Arabic: مُحَمَّد, romanized: Muḥammad; c. 570 CE – 8 June 632 CE) is the founder of Islam and is considered by Muslims to be the last prophet sent by God to humanity. He is also regarded as a prominent religious, political, and military leader. Born in Mecca (modern-day Saudi Arabia), Muhammad began receiving revelations from God (Allah) at the age of 40, which were later compiled into the Quran, the holy book of Islam. His teachings and actions form the basis of Islamic law (Sharia) and tradition (Sunnah). Muhammad's message initially faced opposition, leading to his migration (Hijrah) from Mecca to Medina in 622 CE, which marks the beginning of the Islamic calendar. In Hebrew, Muhammad is referred to as מוחמד (transliterated as Mukhammad), and in Persian, he is known as محمد (Mohammad). His life and legacy have had a profound impact on the world, shaping the religious, cultural, and political landscape of numerous societies.
