Mishkat al-Masabih 6192

Anas told that when Safiya heard Hafsa had called her a Jew's daughter she wept. God's messenger came in where she was while she was weeping and asked her what was making her weep, and when she told him Hafsa had called her a Jew's daughter the Prophet said, "You are a prophet's daughter, your paternal uncle[*] was a prophet, and you are married to a prophet, so what has she to boast of over you?" He then said, "Fear God, Hafsa." *Mirqat, 5:615, indicates that there is a difference of opinion as to whether this means Ishmael or Moses. Tirmidhi and Nasa'i transmitted it.
