for anyone who needs to do so, and no one should take anything from it unless necessity requires. He may give his animals as much fodder as he wishes and may eat whatever he likes, and none of the food, condiments, or fodder consumed while they remain in enemy territory counts as ghulūl (illicit plunder). This is because God has permitted it as part of the war booty through the tongue of the Messenger of God—may God bless him and grant him peace—as conveyed both by trustworthy solitary reports and by the consensus of transmitters. Accordingly, it is lawful to take such provisions with the commander’s permission or without it, and the same ruling applies to whatever they need of mounts and weapons as long as the fighting continues.
Whoever takes any of these items and later has no need of them must return them to the spoils. Mālik said that one should give a large amount of it in charity and keep only a small portion for himself; others said he may consume it whether the amount is little or much—but the first view is sounder. He is not allowed to sell it; if he does sell it, the price must be placed with the spoils, for keeping the proceeds would be ghulūl.
Likewise, anything that is permissible in enemy lands and not owned by any of them—such as game animals, attractive stones, or trees growing on unclaimed wasteland—may be taken without blame. This is the strongest opinion on the matter. God knows best.
