Shabbat 138B

כילת חתנים מותר לנטותה ומותר לפורקה.

With regard to a bridegroom’s canopy, which has no roof but is entirely sloped, it is permitted to spread it and it is permitted to dismantle it on Shabbat.

אמר רב ששת בריה דרב אידי: לא אמרן אלא שאין בגגה טפח, אבל יש בגגה טפח ⁠— אסורה. וכי אין בגגה טפח נמי לא אמרן אלא שאין בפחות משלשה סמוך לגגה טפח, אבל יש בפחות משלשה סמוך לגגה טפח ⁠— אסור. ולא אמרן אלא שאין בשיפועה טפח, אבל יש בשיפועה טפח ⁠— שפועי אהלים כאהלים דמו. ולא אמרן אלא דלא נחית מפוריא טפח, אבל נחית מפוריא טפח ⁠— אסור.

Rav Sheshet, son of Rav Idi, said: We only said that it is permitted in a case where its roof is not a handbreadth wide; however, if its roof is a handbreadth wide, it is prohibited. Furthermore, even when its roof is not a handbreadth wide, we only said that it is permitted where there is not the width of a handbreadth within 3 handbreadths of its roof; however, if it expands to the width of a handbreadth within 3 handbreadths of its roof, it is prohibited. And we only stated that it is permitted where there is not in its incline the width of a handbreadth; however, if there is in its incline the width of a handbreadth, it is prohibited. This halakha is in accordance with the principle that the inclines of tents, even though they are not actual roofs, are considered like tents. And we only said that this canopy is permitted where no part of the canopy descends to a handbreadth below the bed; however, if part of the canopy descends to a handbreadth below the bed, it is prohibited, as the bed itself becomes a roof, and the curtain is considered a wall.

ואמר רב ששת בריה דרב אידי: האי סיאנא שרי. והאיתמר: סיאנא אסור! לא קשיא: הא דאית ביה טפח, הא דלית ביה טפח.

And Rav Sheshet, son of Rav Idi, also said: Wearing this felt hat is permitted on Shabbat, even though it has a wide brim and is similar to a tent. The Talmud raises a difficulty: Wasn’t it stated elsewhere that it is prohibited to wear a felt hat on Shabbat? The Talmud answers: This is not difficult: This latter statement, which prohibited wearing the hat, is referring to a case where its brim has the width of a handbreadth wide and is similar to a tent. That statement by Rav Sheshet, which permits wearing the hat, is referring to a case where its brim does not have the width of a handbreadth.
