אמר רבי חייא בר יוסף רב זן מחיטי דעלייה איבעיא להו פרנסה הויא ומאי עלייה מעילוייא דאב וכדשמואל דאמר שמואל לפרנסה שמין באב

Hiyya b. Yosef stated: Rav provided sustenance [to daughters] from wheat taken from the “aliyah.” They asked: Was [Rav’s provision made for] a dowry, and what is “aliyah?” From the best that the father would have given, and this would be like Shmuel, for Shmuel said that in respect of dowry the assessment is determined by [the disposition of] the father.
