The Battle of Badr fought on Saturday, 13 March 624 CE in the Hejaz region of western Arabia (present-day Saudi Arabia), was a key battle in the early days of Islam and a turning point in Muhammad's struggle with his opponents among the Quraish in Mecca. The battle has been passed down in Islamic history as a decisive victory attributable to divine intervention, or by secular sources to the strategic genius of Muhammad. It is one of the few battles specifically mentioned in the Quran. Most contemporary knowledge of the battle at Badr comes from traditional Islamic accounts, both hadiths and biographies of Muhammad, recorded in written form some time after the battle. The Muslim victory also signaled to the other tribes that a new power had arisen in Arabia and strengthened Muhammad's position as leader of the often fractious community in Medina.
