My revered father-in-law, the Rebbe [Rayatz], once related1 that certain chassidim of the Tzemach Tzedek used to lend each other money — not because they were needy, but because they appreciated the lofty standing of the mitzvah of giving interest-free loans!

[The Rebbe concluded:] May G‑d grant that loans be given not because of need, but only because people appreciate the lofty standing of the mitzvah of giving interest-free loans.

[The Rebbe then handed the warden his own monetary participation in the fund.]
