As the season of coughing and sneezing is upon us, we request from everyone to cover up when they cough or sneeze!
The ashes of a stove are not considered muktzeh and may be used for this purpose. 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.
We Learned in a Beraisa also thus: When it was taught that stove ashes are considered muchan, it was only said with regard to ashes that were burned before Yom Tov. If they were burned on Yom Tov, these ashes are forbidden. If, however, these ashes are still hot enough to broil an egg on them, they are permitted.
If one brought earth into his garden or a ruined shed near his house [for use to cover up spit and the like], it may be used for kisui [if it is scattered on the ground, it returns to muktzeh status but if it is heaped in one spot for use, it remains muchan].
Rav Yehuda: One can bring a basket full of dirt in, and use it for all his needs.
Mar Zutra announced in a lecture, quoting Mar Zutra Rabbah: This is only if he assigned a corner for this dirt.
Challenge: Beraisa: A koy [a buffalo, which is possibly a beheima - not necessitating kisui, and possibly a chaya - necessitating kisui] should not be shechted on Yom Tov [so that we don’t go through the (possibly unnecessary) trouble of kisui]. If it was shechted, it may not be covered with earth.
If what we learned is true, why can’t kisui be done in accordance with Rav Yehuda’s teaching?
Response: What about stove-ashes, or a stick stuck in the ground from before Yom Tov [two scenarios clearly permitted by the Mishna 001]?
You would respond that these are not available, so too, perhaps he doesn’t have prepared dirt.
Challenge: If we’re discussing a scenario where he doesn’t have anything prepared, why mention a koy? In such a case he shouldn’t shecht even a deer!
Resolution: It is obvious that a deer should not be shechted. We might have thought that a koy may be shechted since it is possible that it doesn’t need kisui and we would permit the safek because of simchas Yom Tov, this beraisa teaches that this is not correct.
