Section: Whatever stones are in the land that were created within it, or are built upon it, such as the foundations of ruined walls, belong to the purchaser through the sale; for they are part of its constituents, and thus are like its walls, its soil, and the solid mineral deposits within it. Brick is like stone in this regard. If the purchaser was aware of this, he has no option to rescind. If he was not aware of it, and it causes harm to the land and diminishes it—such as rocks that are harmful to the roots of trees—it constitutes a defect, and the purchaser has the choice between rescinding and taking back the price, or keeping it and taking the compensation for the defect, just as with other sold items. However, if the stones or bricks were deposited there for the purpose of being moved away, they belong to the seller, like a treasure, and it is his duty to move them, level the ground once he has moved them, and repair the holes; for it is a harm that occurred due to the restoration of his property, so it was his duty to remove it. If extracting them causes harm to the land, or takes a long time, and the purchaser was not aware, he has the option as we have mentioned, because it is a defect. If there is no harm in moving them, and it is possible to move them in a short number of days, such as three or less, then he has no option, and he has the right to demand that the seller move them immediately, for there is no custom of leaving them there, unlike crops. If he was aware of the situation, he has no option, nor is there any rent due for the time during which they were moved; because he knew of this and accepted it, so it is similar to if he had bought land containing crops. If he did not know, and chose to keep the sold item, is he entitled to rent for the time of removal? There are two views: One is that he is entitled to it, because usufructs are guaranteed against one who destroys them, so he is liable for their equivalent, like the components. Second: it is not mandatory, because when he accepted keeping the sold item, he accepted the loss of the usufruct during the time of removal. If he did not choose to keep it, and the seller said: "I will leave that for you," and it was something whose remaining caused no harm, he would have no option; for the harm has been removed from him.
