Nudbah, the freed slave-woman of Sayyidah Maymunah (may Allah be pleased with her), said: I went to Ibn Abbas (may Allah be pleased with them both); Maymunah (may Allah be pleased with her) had sent me to him. I saw that there were two (separate) beds in his house. So I returned to Maymunah (may Allah be pleased with her) and said: I think that Ibn Abbas has cut himself off from his wife. So Maymunah (may Allah be pleased with her) sent a message to the wife of Ibn Abbas, the daughter of Mishrah al-Kindi, asking her, and she said: There is no estrangement between me and him; rather, I am menstruating. So Maymunah (may Allah be pleased with her) sent a message to Ibn Abbas (may Allah be pleased with them both): Do you turn away from the Sunnah of the Messenger of Allah (peace and blessings be upon him)? The Messenger of Allah (peace and blessings be upon him) used to touch any of his wives while she was menstruating, with a cloth wrapped around her up to the knee or to the middle of the thigh.
Ibn Jurayj narrated it from Ibn Shihab, from Habib the freed slave of Urwah, from Nudbah.
