Musannaf Ibn Abi Shaybah

Hazrat Nafi’ (may Allah have mercy on him) narrates that a son of Hazrat Abdullah bin Umar (may Allah be pleased with them both) married a daughter of Hazrat Ubaidullah bin Umar (may Allah be pleased with him). The name of the girl's mother was Asma bint Zaid bin Khattab. This son of Hazrat Ibn Umar (may Allah be pleased with them both) passed away before the dowry (mahr) was fixed. The girl's family demanded the dowry and inheritance from Hazrat Ibn Umar (may Allah be pleased with them both). Hazrat Ibn Umar (may Allah be pleased with them both) said that she would receive the inheritance but not the dowry. When people objected to this statement of Hazrat Ibn Umar (may Allah be pleased with them both), he appointed Hazrat Zaid bin Thabit (may Allah be pleased with him) as an arbitrator, and Hazrat Zaid said that she would receive the inheritance but not the dowry.
