Mohammed, also spelled Muhammad, was born in 570 CE in Mecca, present-day Saudi Arabia. He is regarded as the founder of Islam and is considered the last prophet in a line that includes figures like Abraham, Moses, and Jesus. At the age of 40, he began receiving revelations from Allah through the angel Gabriel, which were later compiled into the Quran. Throughout his life, Mohammed preached about monotheism, social justice, and moral conduct. He faced opposition in Mecca but eventually migrated to Medina in 622 CE, an event known as the Hijra. His teachings and leadership helped establish a large Muslim community, and he passed away in 632 CE.
