Nafi' (may Allah have mercy on him) says that the daughter of Ubaydullah bin Umar, whose mother was the daughter of Sayyiduna Zayd bin al-Khattab (may Allah be pleased with him), was married to a son of Sayyiduna Abdullah bin Umar (may Allah be pleased with them both). He died before consummating the marriage and before a dowry was fixed, so her mother demanded her dowry. Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "She has no dowry; had she been owed a dowry, we would not have withheld it from you, nor would he have wronged her." The woman refused to accept this, so they made Sayyiduna Zayd bin Thabit (may Allah be pleased with him) arbiter, and he ruled that she receives inheritance but no dowry.

Sulayman bin Yasar (may Allah have mercy on him) says: Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) married his son to his brother's daughter while his son was still young at that time, and no dowry was fixed. After living for some time the boy died, and the girl's maternal uncle brought the dispute with Ibn Umar before Sayyiduna Zayd bin Thabit (may Allah be pleased with him). Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: I married off my son intending to do good for him, but he died before that, and no dowry had been fixed for the girl. Sayyiduna Zayd bin Thabit (may Allah be pleased with him) said: The girl will receive inheritance if the boy had wealth, and she must observe the waiting period, but she will not receive a dowry.
