Shabbos11: 6
הַזּוֹרֵק, וְנִזְכַּר לְאַחַר שֶׁיָּצְתָה מִיָּדוֹ; קְלָטָהּ אַחֵר; קְלָטָהּ כֶּלֶב; אוֹ שֶׁנִּשְׂרְפָה; פָּטוּר. זָרַק לַעֲשׂוֹת חַבּוּרָה בֵּין בְּאָדָם וּבֵין בִּבְהֵמָה, וְנִזְכַּר עַד שֶׁלֹּא נַעֲשָׂה חַבּוּרָה, פָּטוּר. זֶה הַכְּלָל: כָּל חַיָּבֵי חַטָּאוֹת אֵינָן חַיָּבִין עַד שֶׁתְּהֵא תְחִלָּתָן וְסוֹפָן שְׁגָגָה. תְּחִלָּתָן שְׁגָגָה וְסוֹפָן זָדוֹן, תְּחִלָּתָן זָדוֹן וְסוֹפָן שְׁגָגָה, פְּטוּרִין, עַד שֶׁתְּהֵא תְחִלָּתָן וְסוֹפָן שְׁגָגָה.
One who threw [something], and reminded himself after it had left his hand; [or] another [person] caught it; [or] a dog caught it; [or] it was burnt [in flight]; he is exempt. [If] one threw [a stone] with the intention of inflicting a wound upon either a man or a beast, and he reminded himself when the wound had not yet been inflicted, he is exempt. This is the rule: All who are liable for sin offerings are not liable unless the be-ginning and the end of their acts are [both] inadvertent. [If] their beginning was in-advertent but their end was intentional, [or if] their beginning was intentional but their end was inadvertent, they are exempt, unless their beginning and their end are inadvertent.
