Q. On question 2712 you wrote that on Shabbat one can lean on the tree slightly, when not moving it. but one can’t place a siddur on a tree. Can one leave his chair leaning slightly on a tree on an angle, so it will not get wet it rains?
A. Horav Shlomo Miller’s Shlit’a opinion, as explained by Horav Aharon Miller Shlit’a is that one should not leave a chair even slightly leaning on a tree, since this would be considered “mishtamesh beilon” or using a tree. As opposed to one leaning a bit on a tree, that is permitted when the tree does not move or shake, since one has control of his body and can immediately stop inclining on it.
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit’a
