The other alternative...
The other alternative, which was actually adopted on the recommendation of the Prophet as guided by God, was to leave the booty alone and to march out boldly against the well-armed and well-equipped Quraishite army of 1,000 men coming from Mecca.
This situation is described in the following ayats of the Qur'an: Just as your Lord caused you (O Prophet!) to go forth from your house with the truth, though a party of the believers were averse, they disputed with you about the truth after it had become clear, (and they went forth) as if they were being driven to death while they looked (at it).
And when Allah promised you one of the two parties that it shall be yours, and you loved that the one not armed should be yours, and Allah desired to manifest the truth of what was true by His words and to cut off the root of the unbelievers. That He may manifest the truth of what was true and show the falsehood of what was false, even though the guilty ones disliked it.
(Qur'an, 8:5-8) These verses clearly show that the Meccan army was already on its way long before the Muslims came out of Medina to defend themselves. Also, they clearly show that although some Muslims desired to avoid the Meccan army and to attack the trade caravan, that idea was not accepted, and that the decided aim and objective of their march was to fight the Meccan army which was already on its way.
This clearly belies the vicious and mischievous propaganda of Western writers who claim that the Prophet had intended to attack the trade caravan of the Quraish and that the Quraish had come out only to protect their caravan. The verses of the Qur'an are the only contemporary record of the events of Badr. If there is any writing by anyone, which goes against this authentic narrative, it must be thrown out of window.
You may wonder why the enemies of Islam labor so much to present this battle of Badr as one in which the Quraishites (poor souls!) were aiming just to protect their trade caravan.
The reason is this: It was the first battle between the Quraishites and the Muslims, and if the responsibility of this first battle is laid on the heads of the Muslims, then all subsequent battles could be portrayed as being the continuation of this battle and, thus, the Holy Prophet could be presented as a warrior prophet who by his plundering designs compelled the "peace-loving" Meccans to fight! Anyhow, let us go back to our narrative.
