Saʽd ibn ʽUbadah, born in the year five hundred eighty, was a distinguished politician and color guard in early seventh century Medina. He emerged as a prominent leader within the Sa'ida clan of the Khazraj tribe, eventually rising to the esteemed position of chief of the entire Khazraj tribe and later becoming the leader of all the Ansar.
A close companion of the Islamic prophet Muhammad, Saʽd played a significant role in the early Islamic community. His leadership and dedication to the cause of Islam were evident during his time, as he actively participated in the formative years of the Muslim community.
Following the death of Muhammad in six hundred thirty-seven, Saʽd made an ambitious yet unsuccessful attempt to nominate himself as the caliph of Islam. This moment reflects his deep commitment to the leadership of the Muslim community and his desire to uphold the values and teachings of Islam.
