Musannaf Ibn Abi Shaybah

Hazrat Abu Hurrah Raqashi narrates from his uncle that during the days of Tashreeq, I was holding the reins of the camel of the Holy Prophet (peace and blessings be upon him) and was keeping people away from it. The Prophet delivered a sermon and said: O people! Every wealth and every sign that existed in the time of ignorance is under my feet until the Day of Judgment. The very first blood that has been forgiven is the blood of Rabee’ah bin Harith bin Abdul Muttalib. And Allah Almighty has decreed that the first usury to be forgiven is the usury of Abbas bin Abdul Muttalib. For you is your complete wealth; neither will you oppress nor will you be oppressed.
