Question:
If a hat is hanging on a tree on Shabbos, and subsequently falls off by itself or is removed by a goy, may one wear this hat on Shabbos? I remember learning in Rabbi Simcha Bunim Cohen’s sefer that an object on a tree bein hashemashos is muktzah the whole day, since it is forbidden to remove the object from the tree so it is, for all intents and purposes, “set aside” from being used.
Answer:
Same as a Shofar
