The souls that the Truth bought in this verse are the animal souls that He bought from the rational, believing souls. The rational souls of the believers are the seller and owner of these animal souls that the Truth bought from them, because they are the ones for which killing is permissible, and these souls are not a place of faith. Rather, what is described as faith are the rational souls, and from them He bought the Truth. The souls of bodies, and he said, He bought from the believers, which are the rational souls described by faith, their souls, which are their sensory vessels, and they go out to fight with them and struggle. The believer does not have a soul, so he has no compassion for it except the intrinsic compassion that is in the rational soul for every animal .
