Musannaf Ibn Abi Shayba 13:2374

Abu Bakr narrated to us, he said: Ibn Abi Za’idah narrated to us, from Dawud, from Bakr, who said: A man from the people of the desert married off his daughter, and her dowry was driven [to her], and she took possession of it. Then he died, and her brothers disputed with her regarding her dowry before Umar ibn al-Khattab. Umar said: "As for what you found of your dowry remaining in its essence, it is yours. And as for what your father had consumed, there is nothing for you."
