“From all the commandments of Hashem” — doubtful me’ilah is exempt from asham talui; only a matter whose intentional form is karet and whose shogeg is chatas.
In the sugya: Asham talui is limited to cases in which the intentional violation would carry karet and the unwitting violation would require a chatas. Me’ilah lacks that structure, so a doubt about me’ilah does not generate asham talui.
Type of Learning
Hekesh to chatas liability structure — only sins with karet/chatas profile trigger asham talui.
What Is Learned
Me’ilah lacks karet for intentional violation, so its doubt does not produce asham talui. The obligation is reserved for the classic karet/chatas pair of liabilities.
