פירוש על עבודה זרה 39:5

This verse refers to what a Jew may do with meat that was not properly slaughtered. According to R. Meir, it may be given or sold either to a “ger”—the stranger, which here probably refers to someone who has accepted upon himself to observe some of the commandments, or to an idolater. But R. Yehudah says it must be given to the stranger, but can only be sold to the idolater. Thus we can see that there is a tannaitic dispute over whether one can give a gift to an idolater—R. Meir permits and R. Judah does not.
