Musannaf Ibn Abi Shaybah 38762 — the first to do a thing, and who did

Abu Hurrah al-Raqashi narrates from his uncle, who said: On the middle day of the Days of Tashriq I was holding the rein of the she-camel of the Messenger of Allah (peace and blessings be upon him) and keeping people away from it. He delivered a sermon and said: "O people, all wealth and every mark of honour that belonged to the Jahiliyyah is under these feet of mine until the Day of Resurrection. The first blood remitted is the blood of Rabi'ah bin al-Harith bin Abd al-Muttalib. And Allah Almighty has decreed that the first usury (riba) remitted is the usury of al-Abbas bin Abd al-Muttalib. You shall have your capital; you shall not wrong and you shall not be wronged."
