Maliks Muwatta Book 28, Hadith Number 10.

Section : The Bride-Price and Un-returnable Gifts.

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.
