Nudbah, the freed slave woman of Sayyidah Maymunah (may Allah be pleased with her), narrates that Sayyidah Maymunah (may Allah be pleased with her) sent her to Sayyiduna Ibn Abbas (may Allah be pleased with them both), who was her sister's son. She said: I came and saw that his bed had been moved away from the bed of his wife, the daughter of Mishrah. So I asked: Where is he? Is he angry with his wife? The household said: No, but when she menstruates he keeps away from her. So I went back to Maymunah (may Allah be pleased with her) and told her how I had found him. She said: Call him to me. So I called him, and she said to him: Do you dislike what the Messenger of Allah (peace and blessings be upon him) used to do? By Allah! He (peace and blessings be upon him) would touch one of his wives while she was wearing a garment that reached halfway down the thighs or to the knees.
