Question #1 (Rivan): Does he (R. Yishmael) not hold like the Mishnah in Yevamos (2b) "you cannot say regarding his mother-in-law or the mother of his mother-in-law that they did Mi'un"?

Suggestion: The Mishnah there discusses Kidushin of [orphaned] minors, and here he discusses Kidushei Ta'os, like he taught explicitly.

Rejection: R. Yishmael discusses also Kidushei Ketanah (of an orphaned minor. It is mid'Rabanan, and Rabanan allow her to annul the Kidushin before maturity!)

Proof: His daughter, who came to Mi'un, was a case of Kidushin of minors, for Rav Kahana brought a proof that she may not do Mi'un after bringing hairs, and he said [that they said] "a matter that that Tzadik said, will his descendant stumble in it?!"

Inference: R. Yishmael discusses also Kidushin of minors.

Objection: We could explain "what that Tzadik said" to mean similar to what he said. He said regarding Kidushei Ta'os, and his daughter came to do Mi'un due to Kidushei Ketanos!

Answer: In any case, since [Rav Kahana] said "they voted and concluded, until when may a daughter do Mi'un? Until she brings two hairs";

Inference: They voted and concluded unlike R. Yishmael.

Suggestion: Perhaps [they voted and concluded] unlike R. Yehudah!

Rejection: R. Yehudah admits when she had Bi'ah [after bringing two hairs], and she (R. Yishmael's daughter) had Bi'ah, for her son was on her shoulder!

Question #2: Shmuel holds like R. Yishmael, and he said in Kesuvos (72b) that if one was Mekadesh with a Tenai, and entered her [into his house, i.e. made Chupah] Stam (without mentioning the stipulation), even if he had Bi'ah [with her], she does not need a Get from him;

Does he (Shmuel) argue with the Mishnah in Yevamos (2b)?!

In Kesuvos (73a) we challenge Shmuel from many Mishnayos, and answer them. We did not want to say that he argues with a Stam Mishnah!

Answer: [Indeed,] R. Yishmael argues with the Mishnah in Yevamos (2b), and Shmuel holds like R. Yishmael only regarding Kidushei Ta'os;

However, regarding Kidushei Ketanos, he does not hold like him, rather, like the Mishnah in Yevamos (2b) and of our Maseches, which says "until when may a daughter do Mi'un? Until she brings two hairs ";

Note: A Tosefta (6:5) and a Beraisa (on Amud B) say so.

In Bava Basra (156a), Shmuel explicitly said that we check for Mi'un, to teach unlike R. Yehudah.

Support: This is clear from Yevamos (100b). It asks "can a Mema'enes give birth?!", and answers "through Kidushei Ta'os, like R. Yishmael";

Inference: [Shmuel] holds like him only regarding Kidushei Ta'os, but not regarding Kidushei Ketanah, for there we discuss according to Shmuel.

Implied question: Shmuel said in Yevamos (109b) and Kesuvos (73a) that a minor who did not do Mi'un, and matured, and married someone else, she needs a Get from the second husband;

Inference: She is not Mekudeshes to the first, for she needs a Get from the latter!

Answer: That is mid'Oraisa. Mid'Rabanan, she needs a Get from the first, for once she matured, she cannot leave through Mi'un, like I explained.

Question: Why don't we say that [Rav Chanina and Rav Papa] argue also about oven ash, which is a Shematsa (the Amora's own teaching, not regarding a Mishnah), and [Rav Chanina] says that Rav Malkiya taught it, for Rav Papa said that Rav Malkiyo taught the Shematsos!

Answer: He means that all of these [teachings about] Mishnayos are of Rav Malkiya, and the teachings of Amora'im, some Rav Malkiya taught, and some Rav Malkiyo taught.

Explanation: This refers to growing hair, like it says in Nazir (2a) [if one said] "I will be Mekalkel", he is a Nazir;

Citation (2a) Question: How is this is an expression of growing hair?

Citation (cont.) Answer (Beraisa - R. Yehudah): The Shi'ur of plaster [to be liable for Hotza'ah on Shabbos] is enough for a small Kilkul, and [Rav] said that this is [to remove hair from] the temple (on the face) and below the temple.

Citation (Bava Basra 156a - Rav Nachman citing Shmuel): We check for Chalitzah and Mi'un. This teaches unlike R. Yehudah, who says "until there is more black than white."

There, [the Gemara] rules like all of Rav Nachman's teachings [there] in the name of Shmuel. Also here we say that the Halachah is like all of them, to be stringent.

Pesak: Therefore, she may not do Chalitzah until she brings hairs like the largest [Shi'ur], and until both hairs are in one place, like Rav Ashi;

If she has big breasts like other women, she need not check the lower Siman.

She may not do Mi'un once she brought two small hairs (like the smallest Shi'ur), even if one is on her back and one is between her knuckles.

Pesak: R. Tam wrote in Sefer ha'Yashar that nowadays, once she reaches her years (12), she may not do Mi'un.

Implied question: When he did not have Bi'ah (after 12 years), we ruled above (46a) that we are not concerned lest hairs fell out!

Answer: We are not experts to check the entire body that she does not have hairs, for even one on her back and one on her stomach or between her knuckles join, or mere pores.

Question: Why don't we ask that perhaps all three Grisin she saw in two days, like it says about less than three Grisin?

Answer (Maharam, and so Tosfos found): If we would not attribute [part of the stain] to blood of a louse, rather, we would say that the entire stain came from her body, we would not be lenient to say that she saw on two days, since there is a Shi'ur that can be divided into three sightings;

Therefore, he asked "perhaps she saw two a half in two days", since she saw a little less than three Grisin;

Even though there is more than the Shi'ur of two sightings, you are lenient to attribute the excess to those two sightings, and not to a third sighting;

Also here, when she saw three Grisin and three extra [small] amounts, we should say that two and a half, even though it is more than two sightings, we should say that she saw it in two days, and attribute the excess to blood of a louse.

Question: What is Rava's source that regarding three Grisin in one place, Rabanan are concerned?

Perhaps [they are concerned] only when they are in three places, and she found them in one day, and according to R. Chanina, only on three cloaks, or on one cloak and she found them in three days!

Answer: Rabanan do not distinguish.
