The farewell sermon at Arafat is Islam's self-selected summary, delivered months before the Prophet's death to the largest crowd of his life. It abolishes blood vengeance and usury by naming his own family's claims first, declares Arab superiority over non-Arab and white over black to be nothing except in piety, states obligations toward women, and ends by asking the crowd to bear witness that he delivered the message. Muslims cite it constantly in arguments about racism and rights within the community.
