A ripped tzizit string is mukzah on shabbos. Can one pick it up and put it away if it’s on the floor? For instance in a shul, just like a piece of paper on the floor in order to keep the shul clean?
Answer:
A piece of paper is not muktzeh, provided there is something written on it. A torn tzitzis string, however, is muktzeh, because it no longer serves any purpose. Therefore, it should not be picked up with one’s hand, but rather moved aside with one’s foot, so that it won’t be trampled on, and to keep the shul clean. After moving it aside to a corner, it should be left until after Shabbos, when it can be picked up.
