Beitzah 30B

מתני׳ אין נוטלין עצים מן הסוכה, אלא מן הסמוך לה.

Mishnah: One may not take wood from a sukka on any Festival, not only on the festival of Sukkot, because this is considered dismantling, but one may take from near it.

גמ׳ מאי שנא מן הסוכה דלא ⁠— דקא סתר אהלא, מן הסמוך לה נמי ⁠— קא סתר אהלא?

Talmud: The Talmud poses a question with regard to the Mishnah: In what way is this case different? Why did the Mishnah teach that from the sukka itself one may not remove wood? It is because one thereby dismantles a tent, which is a prohibited labor. But if so, if one takes wood from near it, too, doesn’t he thereby dismantle a tent? Why, then, does the Mishnah permit him to do so?

אמר רב יהודה אמר שמואל: מאי סמוך ⁠— סמוך לדפנות. רב מנשיא אמר: אפילו תימא בשאין סמוך לדפנות, כי תניא ההיא ⁠— באסורייתא.

Rav Yehuda said that Shmuel said: What is the meaning of: Near it? It means near the walls. Wood placed near the walls may be removed because it is not part of the sukka itself; the walls themselves may not be removed. Rav Menashya said: Even if you say that it is referring to a case where the wood is not near the walls but is part of the roof of the sukka itself, when that baraita was taught, it was with regard to bundles of reeds that are not considered part of the roof of the sukka, as they have not been untied. Therefore, one may remove them.

תניא רבי חייא בר יוסף קמיה דרבי יוחנן: אין נוטלין עצים מן הסוכה אלא מן הסמוך לה, ורבי שמעון מתיר. ושוין בסוכת החג בחג ⁠— שאסורה. ואם התנה עליה ⁠— הכל לפי תנאו.

R' Ḥiyya bar Yosef taught the following baraita before R' Yoḥanan: One may not take wood from the sukka itself but only from the nearby wood. And R' Shimon permits one to take wood from the sukka as well. And all agree, even R' Shimon, that with regard to the sukka that was built for the festival of Sukkot, during the Festival it is prohibited to remove wood from it. But if at the outset one stipulated a condition with regard to it allowing him to use it for other purposes, it is all according to his stipulation.
