Sukkah 11B

בעינן כנף בשעת פתיל ⁠— וליכא, קא משמע לן.

we require that it must be a single corner at the time of threading the strand through the hole. And there is not a single corner in this case, as although he ties the fringes separately, he threads the two corners simultaneously. Therefore, Shmuel teaches us that with regard to threading it is not a concern.

מיתיבי: תלאן ולא פסק ראשי חוטין שלהן ⁠— פסולין. מאי לאו: פסולין לעולם, ותיובתא דרב? אמר לך רב: מאי פסולין ⁠— פסולין עד שיפסקו. ושמואל אמר: פסולין לעולם. וכן אמר לוי: פסולין לעולם. וכן אמר רב מתנה אמר שמואל: פסולין לעולם.

The Talmud raises an objection from a baraita: If one attached the tzitzit and did not first cut the ends of their strands, they are unfit. What, is it not saying that the tzitzit are unfit forever with no way to remedy the situation, and this is a conclusive refutation of the opinion of Rav? The Talmud answers that Rav could have said to you: What is the meaning of unfit? It means they are unfit until they will be cut; not that they are unfit forever. And Shmuel said that it means they are unfit forever. And Levi also said: They are unfit forever. And likewise, Rav Mattana said that Shmuel said: They are unfit forever.

איכא דאמרי, אמר רב מתנה: בדידי הוה עובדא, ואתאי לקמיה דמר שמואל, ואמר לי: פסולין לעולם.

Some say that Rav Mattana said: There was an incident that happened to me involving this uncertainty with regard to tzitzit, and I came before Master Shmuel and he said to me: They are unfit forever.

מיתיבי: תלאן, ואחר כך פסק ראשי חוטין שלהן פסולין. ועוד תניא גבי סוכה: ״תעשה״⁠ — ולא מן העשוי. מכאן אמרו: הדלה עליה את הגפן ואת הדלעת ואת הקיסוס וסיכך על גבן ⁠— פסולה.

The Talmud raises an objection to Rav’s opinion from a different baraita: If one attached the tzitzit and only afterward cut the ends of their strands, they are unfit. And furthermore, it is taught in another baraita with regard to a sukka: The verse states: “Prepare for you the festival of Sukkot” (Deuteronomy 16:13), and from the language of this verse the rabbis derived the principle: Prepare it, and not from that which has already been prepared. From here the rabbis said: If one trellised a grapevine, a gourd plant, or ivy over a sukka while still attached to the ground, and then he added roofing atop the vines, the sukka is unfit.
