Muwatta Malik #1254

Yahya related to me from Malik that he heard Rabia ibn Abi Abd ar-Rahman say, ''I heard that the wife of Abd ar-Rahman ibn Awf asked him 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 Awf was ill. When she was purified, she told him and he divorced her irrevocably or made a pronouncement of divorce which was all that he had 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 her idda."
