Question:
If a lender is Jewish but his investor is a non-jew, can a Jew borrow money with interest from him since hundred percent of the money is from a non-jew?
Answer:
My apologies that it took some time to get back to you.
Regarding your question, even though the investor is a non-Jew the money should not be lent to the other Jew without a proper heter iska. The reason is that even though the money came from the non-Jew, since the Jew has liability to return the money to the investor, it is considered like the Jews money now. Even if the Jew doesn’t have liability, it should still not be done because it looks like ribbis. However as stated above that it can be done with a proper heter iska.
