Musannaf Ibn Abi Shaybah 19971 — A man who divorces his wife and she

Abd al-A'la (may Allah have mercy on him) said: Sa'id was asked: If a man marries a woman during her waiting period, then later learns that he married her during her waiting period, and her waiting period has been completed while with him, does her first husband have the right to take her back? After stating the chain, he said that Sa'id bin Jubayr (may Allah have mercy on him) said: "The two of them are to be separated, and the husband has no right to take her back, because her waiting period was completed while she was with this man."
