רב חייא בר אשי

Rav Chiyya bar Ashi was a Babylonian amora whose teachings are preserved throughout the Talmud, most often transmitting the rulings of his teachers Rav and Shmuel. He is cited reciting their words on a wide range of subjects, frequently introduced with the formula “Rav Chiyya bar Ashi said in the name of Rav” or “in the name of Shmuel,” and in several passages he reports firsthand observations of Rav’s practice (“many times I stood before Rav…”).

The cited passages show him engaged primarily in matters of practical halachah. He is quoted on dietary and ritual-purity law in Chullin (e.g., the status of dried figs, the principle that there is a “handle” for impurity but not for rendering susceptible, and a torn thigh-joint rendering a bird treifah), on the laws of festivals and the intermediate days of a festival in Beitzah and Moed Katan, on uncovered liquids and forbidden mixtures in Avodah Zarah, on the writing of a prosbul in Gittin, on washing the hands in Sotah, and on questions of liability in Yevamot and Zevachim. Alongside these legal traditions he also transmits aggadic teachings, such as the statement that Torah scholars have no rest even in the World to Come, and that the barren trees of the Land of Israel will one day bear fruit.

He often appears in parallel with other transmitters of Rav and Shmuel—such as Rav Chanan bar Ami and Rav Chiyya bar Avin—where the chains of tradition are compared and weighed by the Talmud.
