001: Beis Hillel agrees that if he went ahead and slaughtered the animal or bird, he may go ahead and use the stick as permitted by Beis Shammai.
028: When earth was not prepared before Yom Tov, there are three questions involved: 1. Digging. The Melacha of choreish, plowing in a field, or the Melacha of boneh, building - when digging inside a home. 2. Clods of earth cannot be used for kisui hadam, it must be broken up. This involves the Melacha of tochein. 3. Earth is muktzeh. The question is, since eating meat on Yom Tov is a mitzvah, how far do we go to permit these prohibitions?
Rabbi Zrika quoting Rav Yehuda: This is only if the stick had already been stuck into the ground before Yom Tov (prolem #1 above is not relevant).
Challenge: But he is still grinding up the earth! (problem #2 above).
Rav Chiya bar Ashi quoting Rav: The earth being discussed here is loose and does not require grinding. [Tosfos adds that problem #3 is also not relevant, because placing the stick in the ground removes the muktzeh designation].
Challenge: But he’s creating a hollow on Yom Tov [even if the act of digging took place before Yom Tov, the result of creating a hollow - which is forbidden, is being done on Yom Tov].
Resolution: This is in accordance with the ruling of Rabbi Abba.
Rabbi Abba: One who digs a hole on Shabbos in order to use the earth but he doesn’t need the hole, is pattur. [Rashi: Since he is not plowing or digging, he is doing an act of ruination, which is forbidden on Shabbos D’Rabbonon, but one is not liable D’Orayso].
The ashes of a stove are not considered muktzeh and may be used for this purpose.
Question: Who said anything about ashes of a stove?
Rabbah: The Mishna is adding that although no preparation has been made on these ashes, they are always considered muchan.
Rav Yehuda quoting Rav: This is only if these ashes were formed before Yom Tov, but if it happened on Yom Tov, these ashes are considered Nolad. If, however, these ashes are still hot enough to broil an egg on them, they are permitted [they’re not considered Nolad, since they still serve their original purpose of heating and cooking].
