רב אויא חלש ולא אתא לפרקא דרב יוסף. למחר כי אתא, בעא אביי לאנוחי דעתיה דרב יוסף. אמר ליה: מאי טעמא לא אתא מר לפרקא? אמר ליה: דהוה חליש לבאי ולא מצינא. אמר ליה: אמאי לא טעמת מידי ואתית? אמר ליה: לא סבר לה מר להא דרב הונא? דאמר רב הונא: אסור לו לאדם שיטעום כלום קודם שיתפלל תפלת המוספין! אמר ליה: איבעי ליה למר לצלויי צלותא דמוספין ביחיד, ולטעום מידי ולמיתי. אמר ליה: ולא סבר לה מר להא דאמר רבי יוחנן: אסור לו לאדם שיקדים תפלתו לתפלת הצבור? אמר ליה: לאו אתמר עלה אמר רבי אבא בצבור שנו.
After mentioning until when the additional prayer may be recited, the Talmud relates: Rav Avya was ill and did not come to Rav Yosef’s Shabbat lecture. When Rav Avya came the following day, Abaye sought to placate Rav Yosef, and through a series of questions and answers sought to make clear to him that Rav Avya’s failure to attend the lecture was not a display of contempt for Rav Yosef. To this end, he asked him: Why did the Master not attend the Shabbat lecture? Rav Avya said to him: Because my heart was faint and I was unable to attend. Abaye said to him: Why did you not eat something and come? Rav Avya said to him: Does the Master not hold in accordance with that statement of Rav Huna? As Rav Huna said: A person may not taste anything before he recites the additional prayer. Abaye said to him: My Master should have recited the additional prayer individually, eaten something, and then come to the lecture. Rav Avya said to him: Does my Master not hold in accordance with that statement of R' Yoḥanan: A person may not recite his individual prayer prior to the communal prayer? Abaye said to him: Was it not stated regarding this halakha, R' Abba said: They taught this in a communal setting? In other words, only one who is part of a congregation is prohibited from praying alone prior to the prayer of the congregation. Even though Rav Avya was incorrect, the reason for his failure to attend the lecture was clarified through this discussion.
