Translation:Shulchan Aruch/Yoreh Deah/144

Contains two Seif:

The payment for an idol in the hands of a Jew who sold it is prohibited. However, if a non-Jew sold it, even if he sold it to serve it, the payment is permitted, specifically when it is known that he sold it to fulfill his needs with that money. But if it is not known, there is concern that he may have sold it to buy other idols with that money, and thus the coins are designated for idols and are prohibited. (See above at the end of section 132.)

Some say that if a Jew has wine that has been poured for idolatry and idols, and he sells them to a non-Jew on credit (meaning with a delay), and the non-Jew sells them to someone else before he pays the Jew, the payment is permitted retroactively.
