Sayyiduna Jabir (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) the story of the Farewell Hajj, that he (peace and blessings be upon him) said in his sermon: "Beware! Everything of the affairs of the Jahiliyyah has been placed beneath my feet, and all the blood (claims) of the Jahiliyyah are abolished. The first blood among our own blood that I abolish is the blood of Rabi'ah bin al-Harith, that is, Ibn Abd al-Muttalib. He was being nursed among Banu Sa'd when Hudhayl killed him."
