The Arabic term Tsabi (Judaizing Mithrean Nestorian Noahites) or its Greek plural Sobiai also referred to [[Ekhasai]]'s "Hearers" (ismai'i) i.e. the Manicheans' Uninitiated Audience which has caused all Sobiai to be often simply (and inaccurately) referred to as Manicheans even though they were not aware of the "Great Secret" of Mani's Gnosticism. The Persian word for such Tsabis was [[Tazig|Tazig, (pl. Tazigan)]] (perhaps derived from Tarsak) while the Soghdian word was [[Nighòshagàn]].
Tsabians are described in Arabic sources as being between Karaite-Judaizers, Nestorians and Mithrean people of Noah who awaited their "Persian Persia's Messenger". They said la ilaha il allah, used to face a specific direction (perhaps south) to pray the Liturgy of Hours and fasted for the Nativity Fast every year.
Some Tsabis may have been Trinitarians referred to as Mushrikun (practitioners of Shittuf) while others were not.
