"There has already been for you a Sign in the two armies that met (in combat): one was fighting in the cause of Allah the other resisting Allah; these saw with their own eyes twice their number. But Allah doth support with His aid whom He pleaseth. In this is a warning for such as have eyes to see." 352 353
This refers to the battle of Badr in Ramadhan in the second year of the Hijra. The little exiled community of Makkan Muslims, with their friends in Madinah had organised themselves into a God-fearing community, but were constantly in danger of being attacked by their Pagan enemies of Makkah in alliance with some of the disaffected elements (Jews and Hypocrites) in or near Madinah itself. The design of the Makkans was to gather all the resources they could, and with an overwhelming force, to crush and annihilate Muhammad and his party. To this end Abu Sufyan was leading a richly-laden caravan from Syria to Makkah. He called for armed aid from Makkah, The battle was fought in the plain of Badr, about 150 kilometers south-west of Madinah. The Muslim force consisted of only about 313 men, mostly ill-armed, but they were led by Muhammad, and they were fighting for their Faith. The Makkan army, well-armed and well-equipped, numbered over a thousand and had among its leaders some of the most experienced warriors of Arabia, including Abu Jahl, the inveterate foe and persecutor of Islam. Against all odds the Muslims won a brilliant victory, and many of the enemy leaders, including Abu Jahl, were killed.
It was impossible, without the miraculous aid of Allah, for such a small and ill-equipped force as was the Muslim band, to defeat the large and well-found force of the enemy. But their Faith, firmness, zeal, and discipline won them divine aid. Enemy prisoners stated that the enemy ranks saw the Muslim force to be many times larger than it was.
