Jika ia melahirkan anak perempuan, ia najis selama dua minggu, sama seperti pada masa haidnya. Lalu selama enam puluh enam hari ia harus menunggu dalam darah tahir.
Mishnah Keritot
If a woman miscarries on the eve of the eighty-first day: Bet Shammai say: she is exempted from an offering. But Bet Hillel say: she is liable. Bet Hillel said to Bet Shammai: what is the difference between the eve of the eighty-first day and the eighty-first day itself? Since these are considered equal with regard to [blood] uncleanness, why should they not be considered equal also with reference to the offerings? Bet Shammai said to them: No; if you said this in the case where she miscarries on the eighty-first day where it occurred at a time when she was fit to bring an offering, can you say this where she miscarries on the eve of the eighty-first day, where it did not occur at a time when she was fit to bring an offering? Bet Hillel said to them: the case of a woman who miscarries on the eighty-first day which fell on a Shabbat shall prove it, where it did not take place at a time when she was fit to bring an offering and yet she is liable to bring a [new] offering. Bet Shammai said to them: No; if you says this of the eighty-first day which fell on a Shabbat for although it is not fit for offerings of an individual, it is at least fit for communal offerings, would you maintain this concerning a woman who miscarries on the eve of the eighty-first day, seeing that the night is fit neither for offerings of the individual nor for communal offerings? As to [your argument of the uncleanness of] the blood, it proves nothing, for if she aborted within the period of cleanness the blood is unclean, and yet she is exempted from an offering.
Mishnah Niddah
If a woman was in hard labor during the eighty days prescribed for the birth of a female, all kinds of blood that she may observe are clean, until the fetus is born. But Rabbi Eliezer holds them to be unclean. They said to Rabbi Eliezer: if in a case where the law was stringent in regard to blood discharged in the absence of pain, it was nevertheless lenient in regard to blood discharged during hard labor, in a case where it was lenient in regard to blood discharged in the absence of pain is there not even more reason to be lenient in regard to blood discharged during hard labor? He replied: it is enough for the case inferred to be treated in the same manner as the one from which it is inferred. For in what way were you lenient upon her? From the uncleanness of a zivah, but she does have the uncleanness of a niddah.
Mishnah Eduyot
One who takes a vow not to have intercourse with his wife: Beth Shammai says: [after] two weeks [he must divorce her and pay her kethubah], And Beth Hillel say: after one week. A woman has a miscarriage on the eve of the eighty first [day]: Beth Shammai exempt her from bringing the offering, And Beth Hillel do not exempt her. [With regards to the rules of] tzitzit (fringes) on linen sheet: Beth Shammai exempts, And Beth Hillel does not exempt. A basket of [fruit set aside for] the Sabbath: Beth Shammai exempts it [from tithes]. And Beth Hillel does not exempt it.
