Those who said she receives half the mahr

Al-Sha'bi (may Allah have mercy on him) said: If a woman became irrevocably separated from her husband by one or two divorces, then the man married that same woman again and then divorced her without consummating the marriage, the woman will receive half the dower.

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.

Ikrimah (may Allah have mercy on him) and al-Hasan (may Allah have mercy on him) said: If a man separated from his wife by khul', then married her during her waiting period ('iddah), then divorced her before consummating the marriage, the woman will receive half the dower, and she will complete the remainder of her waiting period.

Tawus (may Allah have mercy on him) said: She will receive half the dower.

Maymun (may Allah have mercy on him) said: If a man accepted the ransom for khul' from his wife, then sent her a proposal of marriage, married her and fixed a dower for her, and then divorced her before consummating the marriage, the woman will receive half the dower.

Ja'far (may Allah have mercy on him) said: People other than Maymun used to say: She will receive the full dower.
