Musannaf Ibn Abi Shayba 9:1353

'Abd al-A'la narrated to us, from Ma'mar, from al-Zuhri, that he used to say: If he divorces her before he has consummated the marriage with her while he is ill, then she does not inherit from him, and there is no waiting period ('iddah) upon her, and she has half of the dowry.
