Pesachim 13A

בתוך הנץ החמה ⁠— בגילוייא הוה קאי, וזהרורי בעלמא הוא דחזא. קא משמע לן.

that the incident occurred during sunrise is because he was standing out in the open and they were mere rays of light that he saw which he mistook for sunrise. In actuality, he too is testifying to an incident that occurred before sunrise, and the testimony of the two witnesses is therefore compatible testimony. Rav Shimi bar Ashi therefore teaches us that there is no concern that it transpired in that manner.

אמר רב נחמן אמר רב: הלכה כרבי יהודה. אמר ליה רבא לרב נחמן: ונימא מר הלכה כרבי מאיר, דסתם לן תנא כוותיה.

Rav Naḥman said that Rav said: The halakha is in accordance with the opinion of R' Yehuda. Rava said to Rav Naḥman: And let the Master say that the halakha is in accordance with the opinion of R' Meir, who maintains that one may eat during the entire fifth hour, as the tanna taught an unattributed Mishnah in accordance with his opinion, indicating that this is the halakha.

דתנן: כל שעה שמותר לאכול ⁠— מאכיל!

As we learned in a Mishnah: For the entire time that one is permitted to eat leaven himself, he feeds it to his animal. It can be inferred from this Mishnah that there is no intermediate period when it is prohibited for a person to eat leaven but he may feed it to his animal. This unattributed Mishnah must be in accordance with the opinion of R' Meir, as R' Yehuda maintains that during the 5th hour it is prohibited to eat leaven but one may feed it to an animal.

ההיא לאו סתמא הוא, משום דקשיא ״מותר״.

The Talmud rejects this contention: That Mishnah is not classified as unattributed, as it is in accordance with the opinion of Rabban Gamliel, due to the fact that had the Mishnah been in accordance with the opinion of R' Meir, the term: Permitted, is difficult. Instead, the Mishnah should have been formulated: When one eats he may feed.
