In the month of Ramadan in the second year after the Hijrah (624 CE), the Prophet ﷺ received news that a large trading caravan of the Quraysh, led by Abu Sufyan, was returning from Syria to Makkah. The caravan consisted of around a thousand camels laden with goods, escorted by only thirty to forty guards.
The Prophet ﷺ called on the Muslims to intercept the caravan, and a small group of around 313 Companions was assembled to carry out this task.
Abu Sufyan had meanwhile discovered what the Muslims were planning and sent Damdam ibn Amr al-Ghifari ahead to warn the Quraysh in Makkah and to call for reinforcements. The Quraysh mobilised an army of around 1,000 men, equipped with cavalry (both horses and camels), under the command of Abu Jahl. With great haste they set out for Badr.
Abu Sufyan succeeded in bringing the caravan to safety along an alternative coastal route. He therefore sent word to the Quraysh that the caravan was safe. Yet Abu Jahl refused to turn back. “By Allah, we will not return until we have reached Badr,” he declared.
