Amr bin Maymun bin Mihran (may Allah have mercy on him) narrates from his father that he said: I came to Madinah and asked about the most knowledgeable of its people, and I was directed to Sa'id bin al-Musayyib (may Allah have mercy on him). I asked him about the irrevocably divorced woman, and he said: She is to spend her waiting period in her husband's house. I said: Then what about the hadith of Fatimah bint Qays (may Allah be pleased with her)? He said: Alas for that! And he (my father) described that he was angry, and he said: Fatimah (may Allah be pleased with her) caused trouble for people; she had a sharp tongue (i.e. she was outspoken), and she was abusive towards her in-laws, so the Messenger of Allah (peace and blessings be upon him) ordered her: "to spend her waiting period in the house of Ibn Umm Maktum (may Allah be pleased with him)." Likewise, Abu Mu'awiyah al-Darir narrated it from Amr bin Maymun (may Allah have mercy on him).
