Paying Interest to Tzedakah

By Rabbi Chaim Chazzan


Someone pledged a number of donations to a shul for aliyos he’d received and told the gabbai that he would pay them before Rosh Hashanah. When the year came came to a close, his financial situation was tight, so he assured the gabbai that he would pay up in a few months and add a compensation for the late payment. The gabbai agreed. Does adding money to the original amount due pose a concern regarding the prohibition of interest?


Ordinarily, adding to a sum owed is an outright form of ribbis – interest (ribbis ketzutzah) which is biblically prohibited. However, in our situation, the halacha depends on how we view the nature of the obligation to fulfill a pledge to tzedakah.

When someone promises to give a gift to a friend, no lien is placed on his property, for it is seen as a moral obligation to fulfill one’s word, not a monetary obligation.

Concerning a pledge to tzedakah, the poskim debate whether fulfilling one’s word should be viewed as a moral obligation or as a more severe monetary obligation, comparable to owing someone money.

If the pledge to tzedakah is considered a monetary obligation then the issur of ribbis would apply, but if it is a moral obligation then there is no issur of ribbis.

This person is therefore in a in a quandary. According to the poskim who rule that ribbis does not apply, he is obligated to fulfill his pledge, including the added amount; but according to those who do apply the issur of ribbis, he is prohibited to give the added amount he had pledged.

The solution therefore is the following: At first, he should only pay the amount of the original pledges. The following day, he should give the added amount he had pledged and stipulate: “If there is no issur of ribbis then I am paying to fulfill my word; however, if there is an issur of ribbis, I am now donating this money to tzedakah, unrelated to my previous statement.” As such, he will be giving the money without any concern.

One may ask: How is this different than giving a gift given after returning a loan, which is forbidden? The answer is: Usually we assume that the gift is being given for the loan, and is therefore a form of ribbis. Here, the money is being given due to a sofek that he may be obligated to give, and therefore it has no resemblance to ribbis.
