Ribbis? Easy! That means interest on a loan. That's all. Right? Wrong! Ribbis can mean many things, and its law can affect everyone from students to homemakers, including many practices that people have been taking for granted all their lives. Not that everything is forbidden very often there are right ways and wrong ways to do them. In this pathfinding book, one of our generation's most distinguished teachers presents the laws and shows how they relate to everyday situations. Gifts? Heter Iska? Borrowing sugar or eggs? Pre-payment discounts? They are all here, in this major, enlightening, profusely footnoted masterpiece. Foreword by Rabbi Avrohom Pam. Includes Heter Iska Forms.
