Muktzeh is a concept in Jewish rabbinical law (Halakha). Muktzeh objects are subject to use restrictions on the Sabbath. The generally accepted view regarding these items is that they may be touched, though not moved, during Shabbat or Yom Tov. Some extend this prohibition to the actual handling of these items. Halakha defines various categories of objects or substances which are "set aside" on the Jewish Sabbath, as well as various permissible instances of moving these various muktzeh items. For example, one may not handle money, rocks, twigs, etc. on Shabbat, as these items are muktzeh.
