I muri i te hinganga o te mana o Umayyad i nga kawanatanga rawhiti o te caliphate i muri i te matenga o Caliph Yazid, ka neke a Abbad me 2,000 o ana "mawālī" (kore-Arab, Muslim freedmen, kaihoko ranei) ki Hiria i reira i whawhai ai ratou i te taha o te ope a te caliph Umayyad a Marwan I i te Pakanga o Marj Rahit
i te tau 684. Hei rereke, e kii ana a Zetterstéen ko te roopu o Abbad i Marj Rahit ko ona ake whanaunga. Whai muri i te wikitoria nui a Umayyad i te pakanga, i whai a Abbad ki te reti ki te taone nui o te raki o Arapia o Dumat al-Jandal, engari i tukuna ia e Caliph Abd al-Malik ki te tu atu ki tetahi rangatira o te rangatira o Kufa-based, pro-Alid rebel al-Mukhtar al-Thaqafi i etahi wa i mua o te 687. I muri mai ka tohutohu a Abbad ki a Caliph al-Walid I () i te wa i ngana ai te whakamutunga ki te whakakapi i te tuakana o te caliph a Sulayman i roto i te rarangi o te whakatipuranga me te tama a al-Walid a Abd al-Aziz. Ahakoa e kii ana a Zetterstéen kaore i te mohiotia te ra o te matenga o Abbad, ko nga kaituhi a I. K. A. Howard me Khurshid Ahmad Fariq e kii ana i mate a Abbad i te 718/19.
