Beraisa: If a city contains idolaters and Jews, if the idolaters give donations to the Gabbaim, they may collect from them and from Jews and distribute them money to poor idolaters and poor Jews.

One may visit sick idolaters and sick Jews; one may comfort mourners who are idolaters and Jewish mourners; one may bury dead idolaters and dead Jews; one may bring in utensils (that have been left in the street and will be lost) of idolaters and Jews; all of these are in order to have peaceful relations with the gentiles.

Question (Weavers/people of Girda to Rabbi Ami): May one visit an idolater on his wedding day?

R. Ami thought to permit it in order to have peace. R. Ba said to him - R. Chiya taught in a Beraisa that the wedding day of idolaters is prohibited...?

R. Ami: If not for R. Ba, we would have permitted possible idol worship (as the visiting could lead business dealings which could lead the idolater to thank his idol).
