 Both tribes were massive and compared to nations by historian Amar S. Baadj.The Sulaymi tribes or sub-tribes that were expelled to Upper Egypt consisted of the Hayb, Labid, Dabbab, Awf, Zughba and Rawaha; each of these contained numerous clans.Medieval Muslim chroniclers report that in 1050 or 1051, the Sulaymi and Hilali nomads were dispatched or encouraged to migrate to and take over Ifriqiyah by the Fatimids to punish that region's Zirid rulers for switching allegiance to the rival Abbasid Caliphate.
