Muhammad, also spelled as Mahomet, is the founder of Islam. He is considered the final prophet in Islam and is believed to have received revelations from God, which were later compiled into the Quran, the holy book of Islam. Muhammad was born in Mecca, in present-day Saudi Arabia, in the year 570 CE. He belonged to the Quraysh tribe, a prominent Arabian tribe in Mecca. Muhammad's teachings and leadership led to the spread of Islam across the Arabian Peninsula and beyond, and he is highly regarded by Muslims as the "Seal of the Prophets" and the model for living a righteous life according to Islamic principles.
