In Mandaeism, Yufin-Yufafin or Yupin-Yupapin (, ) is an uthra (angel or guardian) in the World of Light. In the Ginza Rabba, Yufin-Yufafin is mentioned in Books 3 and 5.4 of the Right Ginza and Book 1 of the Left Ginza, whereas "Yufin-Uthra" is mentioned in Book 4 of the Right Ginza. He is also mentioned in many Qulasta prayers, including prayers , , , , , , 105, and 171, in which he is often mentioned along with uthras such as Sam Mana Smira and Nbaá¹Â.
Nathaniel Deutsch (2000) links Yufin-Yufafin with Yophiel, one of the names of the angel Metatron in Jewish mysticism. Deutsch also observes many parallels between Metatron and Abatur.
