Babylonian amora of the third century, contemporary of Naḥman (b. Jacob) and of Ammi (B. M. 57a). Though he was a poor man, people trusted him with their treasures, making him their bailee, without taking receipts from him. It is stated that, rumor having spread the report that Ḥasa had been drowned, Naḥman decided that Ḥasa's wife might marry again, on the ground that, were he still alive, the report of the whereabouts of so great a man would certainly have reached Naḥman's ears (Yeb. 121b; Ket. 85b).
