The Day of Battle-badr

At midnight on March 17, the Quraish broke camp and marched into the valley of Badr. It had rained the previous day and they struggled to move their horses and camels up the hill of 'Aqanqal. After they descended from 'Aqanqal, the Meccans set up another camp inside the valley. While they rested, they sent out a scout, Umayr ibn Wahb to reconnoitre the Muslim lines. Umayr reported that Muhammad's army was small, and that there were no other Muslim reinforcements which might join the battle. However, he also predicted extremely heavy Quraishi casualties in the event of an attack (One hadith refers to him seeing "the camels of [Medina] laden with certain death"). This further demoralized the Quraish, as Arab battles were traditionally low-casualty affairs, and set off another round of bickering among the Quraishi leadership. However, according to Arab traditions Amr ibn Hishām quashed the remaining dissent by appealing to the Quraishi's sense of honor and demanding that they fulfill their blood vengeance.

The battle started with champions from both armies emerging to engage in combat. Three of the Ansar emerged from the Muslim ranks, only to be shouted back by the Meccans, who were nervous about starting any unnecessary feuds and only wanted to fight the Quraishi Muslims. So the Muslims sent out Ali, Ubaydah, and Hamzah. The Muslims dispatched the Meccan champions in a three-on-three melee, Hamzah killed his victim on very first strike although Ubaydah was mortally wounded.

Now both armies began firing arrows at each other. Two Muslims and an unknown number of Quraish were killed. Before the battle started, Muhammad had given orders for the Muslims to attack with their ranged weapons, and only engage the Quraish with melee weapons when they advanced. Now he gave the order to charge, throwing a handful of pebbles at the Meccans in what was probably a traditional Arabian gesture while yelling "Defaced be those faces!"The Muslim army yelled "Yā manṣūr amit!" and rushed the Quraishi lines. The Meccans, understrength and unenthusiastic about fighting, promptly broke and ran. The battle itself only lasted a few hours and was over by the early afternoon.. The Qur'an describes the force of the Muslim attack in many verses, which refer to thousands of angels descending from Heaven at Badr to slaughter the Quraish. It should be noted that early Muslim sources take this account literally, and there are several hadith where Muhammad discusses the Angel Jibreel and the role he played in the battle.
