# an object upon which [[Muktzeh]] was left intentionally from before [[Shabbat]] and one intended that it stay there as [[Shabbat]] entered (during [[Bein HaShemashot]]), the object becomes a Bosis. <ref>Kitzur S"A 89:1</ref> | |||
# One may not move a Bosis on [[Shabbat]] even if one needs its place or to use it for a permitted use. <ref>Kitzur S"A 89:1</ref> | # One may not move a Bosis on [[Shabbat]] even if one needs its place or to use it for a permitted use. <ref>Kitzur S"A 89:1</ref> | ||
# If money or any other [[muktzeh]] item was left unintentionally on a table, one may learn on the table on [[Shabbat]] if it isn’t certain that learning there will cause the money to move. <Ref> The Mishnah ([[Shabbat]] 142b) states that if one wants to move a barrel on [[Shabbat]] and a rock was left on top of the barrel from before [[Shabbat]], he may tilt the barrel so that the rock falls off and then move the barrel. The Gemara limits this to a case in which the rock was left unintentionally; however, if the rock was left on top of the barrel intentionally, one may not move the barrel at all, as it is considered a bosis for [[muktzeh]], serving as a support of the [[muktzeh]] item. The Mishnah explains if one isn’t able to tilt off the rock, such as if there’s a fear of it breaking other barrels nearby when it is tilting off, one may move the barrel with the rock on top until one reaches a places where one can safely remove the rock. The Rambam ([[Shabbat]] 25:17), Tur, and S”A 309:4 codify this as Halacha. | # If money or any other [[muktzeh]] item was left unintentionally on a table, one may learn on the table on [[Shabbat]] if it isn’t certain that learning there will cause the money to move. <Ref> The Mishnah ([[Shabbat]] 142b) states that if one wants to move a barrel on [[Shabbat]] and a rock was left on top of the barrel from before [[Shabbat]], he may tilt the barrel so that the rock falls off and then move the barrel.

Halachos of [[Muktzah]] (by Rabbi Bodner, pg 309, answers of Rav Moshe Feinstein #31, to see it inside [http://books.google.com/books?id=bAevcHQwPbsC&printsec=frontcover&dq=laws+of+muktzah&hl=en&ei=XMMATvnWDauu0AHRjonMDg&sa=X&oi=book_result&ct=result&resnum=2&ved=0CC4Q6AEwAQ#v=onepage&q&f=false click here]) writes that if a siddur and money are on a vessel the siddur is considered more important, and so too if one has glasses which one needs immediately and a lot of money, the glasses are more important unless one has other glasses in which case the money is more important. Lastly if a loaf of [[challah]] and money are on a vessel the [[challah]] is more important since you’re going to need it on [[Shabbat]]. This is also the opinion of the Shemirat [[Shabbat]] KeHilchata 20:61 in name of Rav Shlomo Zalman that anything which is needed for that [[Shabbat]] such as [[challah]] or something else of value. [See also Chaye Adam ([[Shabbat]] 66:4) and Magan Avraham 279:5 who seem to hold of this.] </ref> | Halachos of [[Muktzah]] (by Rabbi Bodner, pg 309, answers of Rav Moshe Feinstein #31, to see it inside [http://books.google.com/books?id=bAevcHQwPbsC&printsec=frontcover&dq=laws+of+muktzah&hl=en&ei=XMMATvnWDauu0AHRjonMDg&sa=X&oi=book_result&ct=result&resnum=2&ved=0CC4Q6AEwAQ#v=onepage&q&f=false click here]) writes that if a siddur and money are on a vessel the siddur is considered more important, and so too if one has glasses which one needs immediately and a lot of money, the glasses are more important unless one has other glasses in which case the money is more important.
