(R. Ze'irah citing R. Chaninah): If one was in [the days when one must mention] rain, and he mentioned dew, we do not return him. In [the days when one must mention] dew, and he mentioned rain, we return him.

Question (Beraisa): Chachamim did not obligate mentioning dew and wind. If he wants to mention, he mentions. (Why do we return him if he mentioned rain, and not dew?)

Answer: One who curses (mentions rain at a time when it is harmful) is unlike one who does not pray [for rain] and does not curse.

Question: [R. Ze'irah taught that in the days of] rain, if he mentioned dew, we do not return him. A Beraisa teaches that if he did not request [rain] in Birkas ha'Shanim, or did not mention Gevurah of rain in Techiyas ha'Mesim, we return him!

Answer: [The Beraisa] discusses when he did not mention dew and not rain.

(R. Ze'irah citing R. Chunah): If one did not request [rain] in Birkas ha'Shanim, he says it in Shome'a Tefilah. Similarly, if he did not mention Gevurah of rain in Techiyas ha'Mesim, he says it in Shome'a Tefilah;

Request, which is amidst necessity, [if one omitted it, it suffices to say it] in Shome'a Tefilah. Mention, which is not merely praise, all the more so!

Question (Beraisa): If one did not request [rain] in Birkas ha'Shanim, or did not mention Gevurah of rain in Techiyas ha'Mesim, we make him return!

Answer (Rav Avmari): That is when he did not say it in Shome'a Tefilah.

Question: [If he did not say it in Shome'a Tefilah,] to where does he return?

Answer: It should be like R. Shimon bar Ba said in the name of R. Yochanan - on Rosh Chodesh, if one [omitted Ya'aleh v'Yavo and] uprooted his feet (stepped back), he returns to the beginning, and if not (he did not step back), he returns to Avodah (Birkas Retzei);

Here, if he uprooted his feet, he returns to the beginning, and if not, he returns to Shome'a Tefilah.
