Yahya related to me from Malik that he heard Rabia ibn Abi Abdar-Rahman say, ''I heard that the wife of Abd ar-Rahman ibn Awf askedhim to divorce her. He said, 'When you have menstruated and are pure,then come to me.' She did not menstruate until Abd ar-Rahman ibn Awfwas ill. When she was purified, she told him and he divorced herirrevocably or made a pronouncement of divorce which was all that hehad left over her Abd arRahman ibn Awf was terminally ill at the time,so Uthman ibn Affan made her one of the heirs after the end of heridda."
