Rabbi Chiya bar Abba recounts a discussion between Rabbi Ami and Rabbi Yochanan regarding the legal weight of a minor's intent. In the first version, the question is whether a minor's thoughts alone are significant. Rabbi Ami argues it is obvious they are not, citing a Mishna in Kelim 17:15. Rabbi Yochanan clarifies that the doubt applies when a minor's action reasonably demonstrates their intent, but not completely - such as moving an animal to the northern part of the Temple courtyard, the specific area for slaughtering burnt offerings. Rabbi Ami challenges this, noting that Rabbi Yochanan himself previously ruled in the context of ritual impurity that a minor's action is significant when the minor's intent is reasonably clear from the action. Rabbi Yochanan responds that his question was whether such actions are valid by Torah law or only by Rabbinic decree; the matter remains unresolved.

Rav Nachman bar Yitzchak offers a different version of the discussion, focusing on whether a minor's actions are effective. This version concludes with Rabbi Yochanan distinguishing between three categories: actions with clear intent, actions with reasonably clear, but not completely clear intent, and intent without any accompanying action.

Shmuel asks Rav Huna for the biblical source disqualifying sacrifices that were slaughtered without the specific intent to perform a slaughter (mitasek).

The Mishna rules that meat slaughtered by a non-Jew is considered neveila (a carcass) and imparts impurity by carrying (masa). Rabbi Yochanan and Rabbi Ami draw different inferences from this. Rabbi Yochanan suggests the Mishna follows the Sages (against Rabbi Eliezer) in assuming that gentiles do not automatically slaughter for idolatrous purposes; if they did, the meat would be forbidden even for benefit. Rabbi Ami infers that the slaughter of a heretic (min), one who is a devout idol worshipped is strictly forbidden for any benefit, a position supported by a braita.

The Gemara explains that we generally do not fear a gentile will slaughter for idolatry because they are typically not devout in their practice. However, a min is considered deeply dedicated to their worship, and their slaughter is presumed to be for an idol. Rav Nachman distinguishes between Jewish heretics and gentile heretics, showing more leniency toward the latter, though the Gemara clarifies this applies specifically to accepting their sacrifices.

The shechita of one who slaughters in the dark or a blind person is accepted.
