Yahya related to me from Malik from Nafi that the daughter of
Ubaydullah ibn Umar whose mother was the daughter of Zayd ibn al-
Khattab, married the son of Abdullah ibn Umar. He died and had not yet
consummated the marriage or specified her bride-price. Her mother
wanted the bride-price, and Abdullah ibn Umar said, "She is not
entitled to a bride-price. Had she been entitled to a bride-price, we
would not have kept it and we would not do her an injustice. "The
mother refused to accept that. Zayd ibn Thabit was brought to
adjudicate between them and he decided that she had no bride-price,
but that she did inherit.
