accounts and the role of the Saba'iyya at the Battle of the Camel. Concerning Ibn Saba' religious beliefs, particularly that of the Saba'iyya, W. F. Tucker noted that they are more complete and better recorded in sources devoted to heresiography. Matti Musa points out that the Saba'iyya as a ghulat sect did in fact exist, noting that their views have been seriously considered by both Sunni and Shia heresiographers. Hodgson states that there are contradictions in what religious views is ascribed to him and his followers, but we can assume that he was a founder or a hero of one or more sects called Sabaʾiyya, which exalted the position of Ali. Ancestry M. G. S. Hodgson concludes he was most likely not a Jew. W. F. Tucker suggests the possibility that the attribution of Jewish ancestry to Ibn Saba' on his paternal side and imputation of black descent on his mother's side, were fabricated to discredit his credentials as a Muslim Arab and "thus stigmatize all ideas associated with him". Bernard Lewis states that modern critical scholarship casts doubt on his Jewishness. Citing the example of Ibn Saba', Lewis states that there is tendency in Islamic sources to attribute subversive and extremist doctrines to Jewish origins, conspiracy or instigation. G. Levi Della Vida also rejects his Jewish origin and maintains that Ibn Saba' was an Arab. However, according to Hartwig Hirschfeld, Abd Allah ibn Saba' was a Jew from Yemen who embraced Islam. Israel Friedlander suggested that he may have been a son of an Ethiopian Falasha woman, which explains why he was called "ibn al-Sawdāʾ". W. F. Tucker, after examining the different arguments, concludes that "Whatever is the case regarding his ethnic identity, it is quite probable that Ibn Saba' was a Yemenite, and that he came from a Jewish milieu". Ghulat Traditionally, Abd Allah ibn Sabaʾ is considered as the first of the ghulāt. He may have been the first to deny that Ali had died and predicted his return (rajʿa), which was considered one form of ghulū. Also, the notion of the absence or 'occultation' (ghayba) of an imam seem to have appeared first among the ghulāt. Heinz Halm records him as a representative of a Ghulat group from the city of Seleucia-Ctesiphon (al-Madā'in) who came to see ‘Alī in Kūfah. When Ibn Saba' proclaimed divinity, then ‘Alī denied this angrily and exiled him back to Seleucia-Ctesiphon.
