[If] one slaughters [an animal], and it is found [to be] a treifah, [if] one slaughters for idolatry, or [if] one slaughters a cow used for purification, or a bull sentenced to stoning, or a heifer that is to be decapitated — R’ Shimon exempts him, but the Sages declare him liable. [If] one slaughters [an animal] and it became a neveilah through his hand, or [if] he pierces the nostrils or tears out the throat organs, he is exempt from the law of ‘‘it and its offspring.’’ [If] two [persons] bought a cow and its offspring, whoever bought first may slaughter first, but if the second one preceded him, he has gained the advantage. [If] one slaughtered a cow and afterwards its two offspring, he incurs eighty lashes. [If] he slaughtered its two offspring and afterwards he slaughtered it, he incurs forty lashes. [If] he slaughtered it and its daughter and its daughter’s daughter, he incurs eighty lashes. [If] he slaughtered it and its daughter’s daughter, and afterwards he slaughtered its daughter, he incurs forty lashes. Sumchos says in the name of R’ Meir: He incurs eighty lashes. On four occasions during the year, one who sells an animal to his fellow must inform him, ‘‘I sold its mother for slaughtering,’’ [or] ‘‘I sold its daughter for slaughtering.’’ They are the following: the eve of the last day of the [Succos] festival, the eve of the first day of Pesach, the eve of Shavuos, and the eve of Rosh Hashanah, and according to R’ Yose HaGlili also the eve of Yom Kippur in Galilee. Said R’ Yehudah: When? When he has no time, but if he has time he need not inform him. But R’ Yehudah agrees that if he sells the mother to the bridegroom and the daughter to the bride, that he must inform — it is known definitely that both will slaughter on the same day.
