His statement, “All his baggage is to be burned”: the apparent meaning of his words is that this is obligatory; that is, all his baggage must be burned.
His statement, “except for weapons”: such as a sword, a gun, and the like.
His statement, “and a copy of the Quran”: out of respect for it.
“And whatever has a living soul...”
His statement, “and whatever has a living soul”: because a living creature is not to be punished with fire, such as a camel or a horse. Everything else, however, is burned: such as dirhams—which, like our dirhams today, are paper currency—utensils, a camel’s pack-saddle, a saddle, a lead rope, and the like.
Here we may ask: Why should it be burned? Would it not be better to add it to the booty? Or would it not be better to discipline its owner, for example by beating him, while the property remains his?
The answer is no, because the purpose of this burning is to make an example of the man. The benefit of making an example of him is greater than the benefit of the wealth that would be added to the public treasury or to the booty. Thus, this serves a greater interest than the financial benefit that would have been gained had it not been burned. As for why it is burned rather than destroyed by some other means or given in charity, this is because it is what has been reported from the Companions. Yazid ibn Jabir said: “The sunnah concerning one who unlawfully takes from the booty is that his baggage is burned.” (1)
