The second meaning is: “Why do I see you turning away from it?” That is, you prevent the timber from being placed. “By Allah, I shall surely cast it”—that is, the timber—“between your shoulders.” In other words, if I found nothing upon which to place it except your shoulders, I would place it upon your shoulders. This was because he was the governor.
This is like the statement of Umar ibn al-Khattab, may Allah be pleased with him, to Muhammad ibn Maslamah: “By Allah, I will make it flow, even over your belly.” (1) The case was that a man had two properties, with his neighbour’s property lying between them. He wished to run water from one of his properties to the other, passing through his neighbour’s land. But his neighbour prevented him, saying, “You cannot run water across my land.” Umar, may Allah be pleased with him, compelled him to allow it—that is, to let the water run across his land—because there was no valid benefit in preventing it. The owner of the land would benefit by cultivating and planting along this watercourse as it passed through, and the neighbour would benefit as well. However, if we assume that the neighbour who prevented the water from passing wished to build a house upon the land, then he would have the right to do so. But since it was an orchard, the flow of water would benefit it.
If the owner of the wall were to say, “Do not place the timber until you pay me half its rental value,” the neighbour would not be obliged to pay it, because the wall belongs to the one who built it. If this neighbour agrees to become his partner in the wall and purchase a share from him, he may do so; but if he does not agree, he cannot be compelled. Accordingly, the practice commonly known among people as mubanah is not lawful for the neighbour. Some people, when they build their house and then their neighbour builds beside them, say to him, “Give me half the cost of the wall.” This is unlawful for him, because he built the wall on the understanding that it belonged to him. What, then, makes it lawful for him
