In Mandaeism, Qin (Classical Mandaic: ࡒࡉࡍ) is the mother of Ruha and Zahreil, and grandmother of Ur in the World of Darkness (alma ḏ-hšuka) or underworld.
In Mandaean texts, she is frequently mentioned as the "queen of darkness."
One of her epithets is Sumqaq (Classical Mandaic: ࡎࡅࡌࡒࡀࡒ), which also refers to a well of polluted water in the World of Darkness.
Her husband is the demon Anathan.
[1] In Book 5 of the Right Ginza, Qin gives her daughter Zahreil for Hibil Ziwa to marry.
