it and the one who opens it for the wooden beam fills it back in. Furthermore, necessity calls for the placement of wooden beams, unlike other things.

Section: Whoever possesses the right to place his wooden beams upon a wall, and then it is removed due to its falling, being dismantled, or the wall falling, and then it is restored, he has the right to replace his wooden beams; for the cause permitting its placement is ongoing, so the entitlement to it remains ongoing. If the cause ceases to exist—such as if there is fear for the wall from placing them upon it, or if there is no longer a need for their placement—it is not permitted to replace them, due to the cessation of the permitting cause. If it is feared that the wall might collapse after placing them upon it, [or if there is no longer a need for their placement] (92), he is obligated to remove them, because this causes harm to the owner, and the wooden beams must be removed. If there is no fear for it, but there is no longer a need to keep them on it, he is not (93) obligated to remove them, because there is harm to their owner in removing them, and there is no harm to the owner of the wall in keeping them, unlike the case where there is fear of its collapse.

Section: If one has the right to place his wooden beams on another's wall, he does not possess the right to lend [or rent] (94) it; because he only had that right due to his urgent need to place his wooden beams, and he has no need to place the wooden beams of another, so he does not possess that right. Likewise, he does not possess the right to sell his right to place (95) his wooden beams, nor to reach a settlement regarding it for the owner or anyone else; because it was permitted for him from another's right due to his own need, so it is not permitted for him to do that regarding it, just like another's food if it is permitted to him due to necessity. If the owner of the wall wishes to lend the wall or rent it out in a manner that prevents this entitled person from placing his wooden beams, he does not possess the right to do so; because it is a means to preventing the entitled person from his right, so he does not possess that right, just as he cannot prevent him [outright]. If he intends to demolish the wall without a need, he does not possess the right to do so, because of the forfeiture of the right involved. If he needs to demolish it due to fear of its collapse, or to relocate it to another place, or for a valid purpose, he is entitled to do so; because the owner of the wooden beams only established (96) his right for the purpose of assistance, on the condition of no harm coming to the owner of the wall (97),
