The tribe of Al Said traces its roots to a band of Al Azd through a patrilineal ancestor, al-'Atik al-Asad b. Imran, who settled in Dibba (Dabá), hence the band was also known as the "Azd of Daba". Like other Qahtani, the Azd originally hailed from Yemen and migrated north after the destruction of the Marib Dam. Archeological evidence points to the Sasanid era, around the third or fourth century AD, a period of admittedly weak Persian rule.
