Musannaf Ibn Abi Shayba 34:240

Zayd narrated to us, from Musa ibn Ubaydah, from Sadaqah ibn Yasar, from Ibn Umar, that the Prophet (peace be upon him) praised Him [Allah] with what He is worthy of, then said: "O people, every blood that was in the Jahiliyyah (pre-Islamic era) is void (wasted). And the first of your bloods [to be declared void] is the blood of Iyas ibn Rabi'ah ibn al-Harith, who was being nursed among Banu Layth, and Hudhayl killed him. And the first usury (riba) that was in the Jahiliyyah is the usury of al-Abbas ibn Abd al-Muttalib, and it is the first usury I remit for you. You shall have your capital sums; you will not wrong, nor will you be wronged."
