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."
