The Battle of Badr, the first major battle between the Muslims and Quraysh.

The Battle of Badr or sometimes called The Raid 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, 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 among Muslims as Abu Jahl. The battle marked the beginning of the six-year war between Muhammad and his tribe. The Battle of Badr took place after five or six unsuccessful attempts by the Muslims to intercept and raid Meccan trade caravans between 623 and early 624 CE.

March 13 is the 72nd day of the year in the Gregorian calendar; 293 days remain until the end of the year.
