The killings of Dawud, Ziyad and Sabit, the Salihids' decreased strength after the 468 Vandalic campaign, and the assaults by the powerful Kindites and Ghassanids of Arabia toward the end of the 5th century, all led to the Salihids' weakened status by 502, when the Ghassanids formally became the dominant Arab federates of Byzantium. Afterward, Shahid indicates that the Salihids continued to operate, but were demoted. Between 502 and 529, they likely constituted one of many Arab foederati and directly answered to the dux (governor) of their province or the magister militum per Orientem (commander of the field army of Oriens). This period of time may have been the floruit of Ḥārith ibn Mandala, the last Zokomid phylarch, according to the Jamharat's genealogical table. According to Ibn Durayd, the Tayyid poet Amir ibn Juwayn said in a poem that Harith ibn Mandala went on a raiding expedition, likely on behalf of the Byzantines, against an Arab tribe, possibly the Banu Asad, and never returned.
