Rabi'ah ibn al-Harith RA

Rabi'ah ibn al-Harith RA was a cousin of the Prophet ﷺ, son of al-Harith ibn Abd al-Muttalib. One of his sons, raised among Banu Sa'd, was killed by Hudhayl in a tribal war, leaving an unpaid blood claim. In his sermon at the Farewell Hajj, the Prophet ﷺ cancelled that claim first of all, beginning the abolition of Jahiliyyah blood feuds with his own family.
