Musannaf Ibn Abi Shaybah 18130 — A man who irrevocably divorces

Jabir bin Zayd was asked: "If a man divorces his wife before touching her, and he is told that she has not become forbidden to him, so he has intercourse with her on the basis of the first marriage, and the woman stays with him for two years and bears children, and then they learn that this woman had become forbidden to the man, what is the ruling?" Jabir bin Zayd said: "The two are to be separated. He will give the woman half the dowry on account of the first marriage, and a full dowry on account of the consummation and intercourse."
