Musannaf Ibn Abi Shaybah 19577 — Those who said she receives half

Al-Hasan (may Allah have mercy on him) was asked: If a man made ila' (an oath to abstain) from his wife and she became separated from him, then he married her during her waiting period ('iddah) and divorced her before consummating the marriage, what is the ruling? He said: The woman will receive half the dower, and she will have no waiting period to observe.
