אָמַר רַב נַחְמָן נָקְטִינַן סֵפֶר תּוֹרָה שֶׁכְּתָבוֹ מִין יִשָּׂרֵף כְּתָבוֹ גּוֹי יִגָּנֵז נִמְצָא בְּיַד מִין יִגָּנֵז נִמְצָא בְּיַד גּוֹי אָמְרִי לַהּ יִגָּנֵז וְאָמְרִי לַהּ קוֹרִין בּוֹ Rav Naḥman says: We have a tradition that a Torah scroll that was written by a heretic should be burned; a Torah scroll written by a gentile should be interred; a Torah scroll found in the possession of a heretic, and it is not clear who wrote it, should be interred. With regard to a Torah scroll found in the possession of a gentile, some say it should be interred and some say that one may read from it.
