Commentary for Berakhot 45:2
אמר רב אשי האי אם שהה אם לא שהה מיבעי ליה אלא דכולי עלמא אם שהה כדי לגמור את כולה חוזר לראש והתם בדלא שהה קמיפלגי דמר סבר גברא דחויא הוא ואין ראוי ואין תפלתו תפלה ומר סבר גברא חזיא הוא ותפלתו תפלה
Rab Ashe said : The phrase "If the man has waited" must be altered to "If the man has not waited"; because everybody agrees that if he waited sufficient time to finish the remainder of the Tefillah, he recommences from the beginning; but the point of divergence there [between Rab Hisda and Rab Hamnuna] is the case where the man did not wait. One is of the opinion that the man was in an uncomfortable state and unfit [to pray], and therefore his Tefillah is invalid; while the other is of opinion that the man was fit [to pray] and his Tefillah is valid.
Tosafot on Berakhot
Tosfos offers another proof to his conclusion that the halochoh is that one must return to the beginning. And so too, later (24b)1The Gemara relates that R’ Abuhu was walking behind R’ Yoconon in a filthy alleyway. He stopped reciting sh’ma, and the asked R’ Yochonon, if he must return to the beginning. R’ Yochonon answered that he must. See the Gemara there for the exact circumstances. R’ Abuhu says that one must return to the beginning.
Tosfos will now show that there are contradictions to this conclusion. And this is bewildering for in Maseches Rosh Hashonoh (34b) R’ Yochonon says that if one heard nine blasts of the shofor extended over nine hours of the day, even though there obviously had to be a pause much greater than the time usually required to blow nine t’keeos, he has fulfilled his obligation. We see that those t’keeos that were blown over nine hours combine to complete a mitvoh even though he paused for sufficient time to do all of them, the nine t’keeos.
Tosfos offers a second Gemara that indicates that even though there was a major pause during the mitzvoh, one fulfills his obligation. And so too, in Megiloh (18b) the Gemara also says: Rav said the halochoh is not like Rav Muno who says that if one paused long enough to complete the Megiloh, he must return to the beginning. Because the Gemara says there, in reference to a dispute among the amoraim about what Rav’s opinion was, take hold of Rav Baiboi who says that Rav said the halochoh is not like Rav Muno, in your hand.
We now have two Gemaras that indicate that when one pauses long enough to complete a mitzvoh he must return to the beginning. Our Gemara here and the Gemara on 24b where R’ Abuhu says the same. We have two Gemaras that indicate the exact opposite. The Gemara in Rosh Hashonoh 34b, that discusses blowing the shofor over an extended period and the Gemara in Megiloh 18b that speaks of reading the Megiloh with a major interruption. How can we reconcile these contradictory Gemaros? And the prince of Coucy says that we can differentiate, between the contradictory Gemaras. For here in our Gemara in regard to one who urinated while praying who cannot recite sh’ma while urinating. His ceasing to recite the sh’ma is an interruption because he was not allowed to continue reading. So too, later (24b) where the Gemara is speaking about R’ Abuhu who was walking through filthy alleyways, there where he was not allowed to continue reciting sh’ma while in those alleyways, all agree that he must return to the beginning of sh’ma, since he was required to stop his recital of the sh’ma. However, when the person is eligible, such as by the Gemara discussing a pause while reading the Megiloh and the blowing of the shofor, all agree that he need not return to the beginning, rather, he returns to the place where he stopped. Since there was no need to pause, his voluntary pausing does not constitute an interruption.
Tosfos suggest another solution to the contradictory Gemaras. Our original argument was that the Gemara here could just as easily have said that all agree that after an interruption one need not return to the beginning, and the issue would be if when he started praying while he had the urge to urinate, is he eligible to pray or not. Rabainu Yehudoh disagrees with the idea that the Gemara could just as easily have said that all agree that one need not return to the beginning. And Rabainu Yehudoh explained that here the Gemara could not have possibly said that all agree that one who paused for sufficient time to complete the mitzvoh need not return to the beginning, and that their disagreement would be when he did not2See Rabainu Yonoh who when quoting Tosfos says that the argument would have been when he did not pause long enough to complete the entire shmoneh esray. Tiferes Shmuel favors this text and we have followed it in our interpretation of Tosfos. pause for a long time, and the issue would be if it is considered an interruption because he was not eligible to pray. Because all would agree that he is considered eligible to recite the sh’ma even though he had the urge to urinate when he started praying and he knew that he would not be able to complete the sh’moneh esray, since the rule is that he never returns to the beginning of his prayer3Rabainu Yehudoh seems to understand that when the Gemara speaks of one who has the urge to urinate as being eligible or ineligible, it all centers around whether he will be able to complete the sh’moneh esray or not. He is considered eligible because he can complete the sh’moneh esray. He is considered ineligible because he cannot complete the sh’moneh esray. If so, when we say that no matter how long one paused, he may complete the sh’moneh esray, then there is no longer a situation of being ineligible to start the sh’moneh esray, because one will always be able to complete the sh’moneh esray. The prince of Coucy may have understood that the eligibility or ineligibility is based on a totally different thought. He sees that the ineligibility is because it is not proper to pray when one feels the urge to urinate. It has nothing to do with whether one will be able to complete the sh’moneh esray or not. It is the very fact that he has the urge that renders him ineligible. Even if one holds that one who paused in middle of sh’moneh esaray long enough to complete need not return to the beginning may hold that one who has the urge to urinate is ineligible. when he pauses during prayer for longer than it takes to complete the prayer, no other pausing for whatever reason, such as urine dribbling on his legs is considered an interruption. However, if the Gemara could have said so, that all agree that one who pauses in middle of shmoneh esray need not return to the beginning he certainly would have said it.4According to Rabainu Yehudoh our Gemara is no proof at all that we hold that one who pauses long enough to complete sh’moneh esray must return to the beginning. But what about the Gemara on 24b that Tosfos quoted earlier. See Rosh who shows that the Gemara on 24b is only presenting the opinion of R’ Abuhu, but his teacher R’ Yochonon holds otherwise and we always follow the opinion of a teacher against his student. Hence, there is no proof from our Gemara that it holds that the halochoh is that one who pauses long enough to complete a mitzvoh must return to the beginning of that mitzvoh.
