Some scholars think that Sabin was omitted from the Namelist of Bulgarian Rulers because he was a Slav, but his name could indicate Latin or even Iranian origins. He was related by marriage to Kormisosh, who was either a father-in-law or a brother-in-law of Sabin. Since the relation is by marriage, Sabin would not have actually belonged to the Vokil clan. The 17th century Volga Bulgar compilation Ja''far Tarikh (a work of disputed authenticity) represents Sain (i.e., Sabin) as an usurper, who had deposed Teles (i.e., Telets), and was in turn deposed by the latter''s father-in-law Yumart.
