Laws of Muktzeh on Shabbos
13. It is permitted to move an article that is muktzeh in an unusual manner
(1). Therefore, if one inadvertently left an article that is muktzeh on
top of an article [that is not muktzeh] or such an article fell there on
Shabbos, it may be shaken off (2) or one may carry the [non-muktzeh] item
(with the muktzeh on top) to another place, and then shake off the muktzeh
item there (3).
Similarly, if one inadvertently left money in the pockets of one's clothes,
[one may shake the money from the pockets] if one needs to use the
clothes. One may not, however, do so for the sake of the money alone. (The
laws governing a base for a forbidden article ("bosis le'davar ha'assur"),
on which a muktzeh article was intentionally placed will be explained, G-d
Willing, in the following chapter (4)).
(1) Moving a muktzeh item in an unusual manner is called "titul ke'leachar
yad" (lit: "movement with the back of one's hand") and can be performed
with any part of one's body other than the regular use of one's hands (the
back of the hand is permitted). One is permitted to move the muktzeh object
in an unusual manner even for the sake of the muktzeh object itself, for
example, to prevent it from being damaged.
(2) If shaking it off (" Ni'ur") is feasible, one may not indirectly move
the muktzeh item by carrying it on the non-muktzeh item (Mishna Berura 309:14).
(3) Carrying a muktzeh item on top of a non-muktzeh item is called "titul
min hatzad" ("indirect movement"). As we will see in the next halacha, the
Kitzur Shulchan Aruch only permits this method of moving muktzeh, if it is
for the sake of the non-muktzeh item. However, one can rely on those who
permit it even for the sake of the muktzeh item itself ("Muktzeh; A
Practical Guide" by Rav S.B Cohen).
(4) A non-muktzeh item that is classified as a base to a muktzeh item, may
not be moved on Shabbos (See next chapter for details).
