Abu Hurrah Raqashi narrated from his uncle, he said: I was holding the rein of the camel of the Messenger of Allah (peace be upon him) during the days of Tashreeq and was keeping people away from him, and the Messenger of Allah (peace be upon him) was saying: "Listen, O people! Every kind of usury from the time of ignorance is null and forgiven. Listen! Indeed, Allah the Exalted has decreed that the first usury to be forgiven is that of Abbas bin Abdul Muttalib. For you is your principal amount (i.e., take back only the original amount), neither do you wrong nor will you be wronged."
