The permitted nature of lending to non-Jews with interest: 3 Sub-sections[edit]
159:1 By the strict letter of Biblical law, it is permissible to lend to a non-Jew with interest. Over the generations, the Rabbinic authorities eventually forbade it; if it wasn't crucial for survival or if the Jewish party was a Torah scholar. However, nowadays, it is permissible across the board in any situation (TUR).
159:2 It is permissible to lend to a renegade Jew with interest. However, it is forbidden to borrow from him with interest. NOTE:: Some authorities are stringent and prohibit lending to a Renegade Jew with interest as well (MORDECHAI, HAGHOT MAYMAANI FROM RAAVIYAH AND RASHI, SMAG, MAHARIL). Either way, if avoidable, it is preferable to maintain the stringent opinion.
159:3 A Kuti Jew has the same legal status as a renegade Jew who worships idols. A Karaite Jew does not have the status of a renegade Jew, and it is thus forbidden to lend to one with interest, and certainly it is forbidden to borrow with interest. NOTE:: Earlier, in chapters 157 and 124 the laws of forced situations are discussed. One who was captured by non-Jews as a young child, and is entirely unaware of Jewish law, has the same legal status as a Karaite, and it is forbidden to lend to one with interest (RAMBAM IMPLIED IN BET YOSEF). Likewise, it is forbidden to lend with interest to a son born of the union between a non-Jew and a female renegade Jew who worships idols; since the son is has the same status as his mother (MORDECHAI IN CHAPTER HAKHOLETS). Such a child maintains the aforementioned status of one who was captured by non-Jews as a young child.
