If the plant is one of the thoughts that provide sustenance for the soul, then zakat is due because of the soul’s sustenance. If the sustenance of the soul is dependent on it, then there is no zakat. If the sustenance of this person, whose characteristic is this, then he is God by whom everything is established. It was said to Sahl bin Abdullah, “What is sustenance?” God said. It was said to him, “We asked you about the sustenance of ghosts.” He said, “God.” When they insisted on him, he said, “What do you have to do with it? Leave the land to its owner and builder. If he wishes, he will restore it, and if he wishes, he will destroy it.”
