The Battle of Badr, also referred to as The Day of the Criterion in the Qur'an and by Muslims, was fought on 13 March 624 CE (17 Ramadan, 2 AH), near the present-day city of Badr, Al Madinah Province in Saudi Arabia.
Muhammad, commanding an army of his Sahaba, defeated an army of the Quraysh led by Amr ibn Hishām, better known as Abu Jahl.
The battle marked the beginning of the six-year war between Muhammad and his tribe. Prior to the battle, the Muslims and the Meccans had fought several smaller skirmishes in late 623 and early 624.
